Bought this to test an engine that was creating excessive crankcase pressure. Was told by Dealer the engine needed replacing or repair. Found the compression and leak-down to be very good. So engine appeared to be OK. Found a cracked hose on the brake booster causing the excessive crankcase pressure. This was because the camshaft driven vacuum pump for the booster exhausts into the crankcase. Fixed the hose (replaced) and problem solved. Having this tool to help diagnose the issue saved me 1000’s of dollars. Excellent tool to confirm the overall condition of an engine. This otc 5609 leak down tester would be a great tool to check out a used car if one could take it home and test leak-down. No issues with the OTC 5609 Cylinder Leakage Tester. Thanks.
Worked flawlessly. I had an old Harbor Freight leak down tester I used for a couple years. It worked okay, but it couldn’t hold up to higher pressure. This worked and held 100psi no problem. I wanted to test my engine in my Evo before I threw in a lager turbo, and the otc cylinder leak down tester made it an easy job. Feels solid and varies spark plug connectors that will fit just about all engines, all in a solid blow molded case. OTC is a great trusted brand with a good build quality and good warranty. I suspect this will last me many years.
2. Actron CP7838 Professional Fuel Pressure Tester
This fuel pressure tester diagnoses drivability problems caused by poor fuel pressure. It is designed for fuel injected systems. It features a relief button and a 6-ft hose to safely dispose of gasoline without disconnecting the gauge.
This professional fuel pressure tester kit also works on the throttle body injection with a threaded connection at the fuel filter or throttle body. It is a 2½” gauge with 0-100 psi/0-700 kPa scales for accurate measurements.
The gauge resolution is not optimal for carburetor applications and it does not include any carburetor adapters. To test fuel pressure on carbureted engines, Actron CP7803 Vacuum and Fuel Pressure Tester Kit can be used.
Great tester. I went to one of the popular auto stores to get a rental and I like this one better. The loaner leaked no matter what I tried and was giving me false readings. This is easy to read and has a nice long hose. Nice price as well. My only complaint would be that it does not come in a hard-shell case. It comes with a cheap flat pouch that I find almost impossible to get all the attachments and user manual back in. I have a large lower drawer in my tool chest that I keep all my sensitive testing equipment in so I just carefully toss it in there after use. Would recommend.
This actron professional fuel pressure tester kit thing is to tell you how much fuel pressure you have. It worked but I lost that stupid black cap that does on the nipple. It was a huge pain finding a replacement, and then 6 months later I found the original in my glove compartment, doh. It turned out I had a bad fuel regulator, but this at least help me decide not to replace my fuel pump for no reason. At least I think that’s what I used it for.
This is a good guage for the home mechanic. Kit has adapters for just about any vehicle out, you can even splice into a rubber fuel line if the fuel rail adapter you need isn’t in the kit. My particular vehicle is a Lexus RX300 which is basically a V6 toyota with Lexus decals, this kit came with the proper banjo bolt adapter and sealing washers for me to do the pressure test. The guage is encased in rubber so you can lay it face down on the windshield and check the pressures from inside the vehicle without it sliding down the windshield. The bosch fuel pressure tester kit also has a pressure relief button which is nice to have when your done with your testing. Two things I would want you to do before using the guage for the first time. 1 remove the black test line atached to the guage and wrap the threads in teflon tape. It’s worth 25 seconds of your time to prevent a leak. 2 At the other end of the same black line is a brass fitting, look inside it and you will see a rubber o-ring give it a shot of WD-40. It’s worth another 5 seconds of your time. The extra 30 seconds of prep Gave me a leak free test first use. Happy testing.
3. OTC 5630 Fuel Pressure Test Kit
OTC’s 5630 Fuel Pressure Test Kit quickly and easily locates any malfunctioning fuel system component – fuel filters, pressure regulators, fuel lines, and fuel pumps – without the need to remove it from the vehicle.

A convenient pressure relief valve allows for safe, clean testing. Quickly and easily locate any malfunctioning fuel system components, including fuel filters, pressure regulators, fuel lines, and fuel pumps without removing this otc master fuel pressure test kit from the vehicle.
I suspected my fuel pump was bad in my Mustang due to a crank and no start situation. I was faced with having to have it towed to a shop and paying a diagnostic fee plus repairs and labor. Instead I sprang for this gauge and followed the instructions included, which are very straight forward. Ruled out other issues that cause a fuel pump to fail (looking on Mustang Forums and U Tube). The gauge test showed no pressure and I replaced the fuel pump. Cranks and runs beautifully with great master fuel pressure test kit. I figure what I save in repair costs more than offset the price of this gauge. The gauge is well made. I’ve see higher end gauges, but for the DIY’er it is all you need.
I use this fuel pressure tester master kit now for my Jeep and other friends Jeeps. It is as advertised no more no less so if your a professional mechanic may no meet your expectations…? then again it might? For a weekend warrior it is more than enough. It seems well made and has worked perfect every time I have used it so far. I like the fact the hose is long enough to let pressure off before unhooking the gauge and spill gas safely away from the engine into a jar. I stick the hose into my lawn mower gas can to release the gas into so I don’t have to clean up anything or have extra trash. The numbers for us older peeps on the gauge are easy to see and read and are printed clearly. Cannot say yet how it last since I have not had it that long, but the otc fuel pressure tester master kit appears to be well made enough to last the life of my old heep,… and maybe even me? (: All and all I recommend this to anyone.
4. OTC 5605 Deluxe Compression Tester Kit
OTC’s 5605 Deluxe Compression Tester Kit offers a complete package for compression testing on gasoline engines and comes complete with standard and specialty adapters.

Rugged blow-molded hard case with best compression tester components contained and organized when not in use. Includes repair parts kit.
We bought this for our auto repair shop to do cylinder compression tests. This pittsburgh compression test kit is very professional and has superseded our expectations. This helped us detect bad valves on a 2010 dodge charger. Upon initial testing this helped our mechanic see that 3 valves were losing compression. Then with the customer’s approval for a tear down, it was confirmed that those 3 valves were in deed not seating correctly due to carbon build up. The car had been performing badly with symptoms of running rough at idle and at high speeds. This tool was awesome in helping to pinpoint the problem quickly and accurately I recommend this to all mechanics who do heavy engine work as you will not be disappointed in this piece of equipment!
Same set sold on MAC and Matco trucks. I have only this set with no additional adapters and have always had exactly what I need, right here. I don’t do too much with diesels, so I can’t speak for the coverage there. But for regular automotive use, the actron compression tester kit is all you need. OTC is hit and miss with quality, but this set is spot on. Plus you can warranty or replace the individual pieces with your MAC or Matco dealers as you need them. My coworker has the same MAC set that he paid over $200 for. LOL, He just doesn’t understand. I compared them side by side, and he was still not convinced. Highly recommended for any tech or home mechanic.
5. OTC 5606 Compression Tester Kit for Gasoline Engines
OTC’s 5606 Compression Tester Kit is ideal for use on all types of gasoline engines including domestic, import, motorcycle, marine, and small engines. Professional quality, dual scale 2-1/2 inch diameter gauge reads 0-300 psi and 0-2100 kPa and features a chrome bezel, rugged protective outer boot, and zero adjust feature.
This otc deluxe compression tester kit 5605 includes 12″ flex 14mm standard, 12″ flex 14mm long reach, and 10mm, 12mm, and 18mm thread adapters – adapters work on both flat and tapered seat plugs.
Extra-long 25″ flex hose gauge assembly with quick coupler allows easy viewing out of cluttered engine compartments. Corrosion-resistant nickel-plated finish protects metal components.
I bought the otc compression tester kits 5606 unit to test cylinder compression in my 2001 Buick LeSabre. It’s pretty easy to use and seems to give accurate readings. You just disconnect the fuel injector connectors so there is no electrical current to power them, disconnect the ignition control module, so there is no spark to the spark plugs, remove all the spark plugs from the cylinder heads, screw in the compression tool BY HAND (DO NOT USE TOOLS TO TIGHTEN THE COMPRESSION TESTER INTO THE CYLINDER HEAD THREADS!!) into a cylinder, have someone crank the engine while you check the compression rating on the tool, let the engine crank a few times, then let the best inexpensive compression tester rest. Do this until you don’t see the needle on the gauge go any higher. Write down each compression rating on a piece of paper. Look at all the compression ratings. They should be within 15% of each other. Take your highest compression from your recordings and multiply it by .15. Subtract that sum from your highest rating and that is your lowest possible compression. Meaning if any of your cylinders are lower than your lowest possible compression, that is your problem. OTC has never failed me as far as any tools I’ve bought by them and I give this tool 5 stars for it’s accuracy and ease of use.
Really easy to use. I think this is easier to use than the ones that come with just a cable attached to the gauge because you can screw on the hose easily without having to worry about space requirements with the gauge and worry about hitting anything. Just screw on the hose, then quick attach the gauge, and start your reading. I was not able to test it’s accuracy against other gauges but I was assured it was accurate by a mechanic.
6. Abn Fuel Injection Pressure Test Kit
The new and improved ABN Comprehensive Universal Fuel Pressure Tester Master Fuel Pressure Gauge Kit is a complete fuel test gauge package that quickly tests the fuel pump pressure on injector systems.
This is the best fuel pressure test gauge high-quality fuel pressure gauge hose replacements have been improved with implanted fiber; Fitted with a quick coupling system and pressure release valve fitting with a long drain hose to prevent inadvertent discharge of fuel while testing and to allow for the safe recovery of fuel; Fuel injection pressure gauge displays reading 0-100 PSI and 0 to 7 Bar.
This automotive fuel pressure test kit adapters fuel gauge kit has all necessary fittings to attach to a pressurized system; Will work on any vehicle as long as it has a Schrader test port fuel injection system or as long as you can splice an inline connection; Recommended for older low-pressure systems with mechanical fuel pumps; Not compatible with Bosch, CIS-Jetronic, or GM throttle body systems.
Just wanted to show how to make the automotive fuel pressure tester kit work on fuel rails with a schrader valve. If you look at the hose and fitting connected to the actual fuel pressure gauge there is a a built in adjustable schrader valve on the end (refer to the picture). It ships to you turned completely down. If you take a tire valve remover and rotate the valve counter clock wise it will adjust the valve outward so that it can depress the valve on the fuel rail. These work perfect on GM and other schrader valve fuel rails once you have adjusted it out. Hope it helps.
This is a full set of pittsburgh automotive master fuel injection pressure test kit, in its blow molded case. It comes with all the necessary parts needed to test just about every car made. After buying and receiving it, I was able to check it out and put it to its test. It worked as expected, gave me a clear and to the point pressure reading. It also held the pressure test for over 5 minutes. Which is excellent, since most important fuel pressure test is that. For the pump to be able to hold its pressure for 5 minutes or more. So, in short. If your looking to buy one? ABN has proven to be a serious contender. With its quality parts and price, it will win you over. You can’t/won’t find a better deal for its price. Take it from me, I’ve been in the business, for over 35 years. And still going! This test kit makes it easy for me and the boys at my shop to work and earn our living.
Initially the gauge read 0 pressure on my fuel line, because the Schrader valve stem at the end of the gauge hose was screwed all the way in and wouldn’t reach the Schrader valve stem on the fuel rail of my Jeep Grand Cherokee. I unscrewed the valve stem from the end of the gauge hose using needle nose pliers until it came off. Then I put in the fuel injection pressure tester adapter kit back in just 2 or 3 full turns, and voila, it worked perfectly, 49 psi, the exact spec for the Jeep. While it does not have a fuel relief hose, a shop towel wrapped around the valve works just fine.
7. BETOOLL Fuel Injector Pressure Tester Kit
The BETOOLL Fuel Injector Pressure Tester Kit included adapters, hoses, and fittings cover all fuel injection systems and most cars and trucks worldwide! It has a Fuel Injection Pump Pressure / Oil Combustion Spraying Pressure Gauge Teste.
This marine fuel injector pressure testing Designed for repeated use with high-quality materials for maximum durability. It is a money-saving tool & saves hundreds of dollars on fuel injection tester kit. It’s Measuring range is 0-140psi (0-10 bar).
The gauge will hold pressure values and has a pressure release valve with drain hose for safe fuel recovery. Components of this fuel injector pressure drop test made of high-quality Brass, rugged and long-lasting.
Well, I’ll try to make this short and sweet. I used this Betooll fuel injector pump pressure tester for the first time to check out my father’s 1995 Oldsmobile Delta 88 Royale last week Friday. You know, I didn’t even have to use any of the other fittings that came with the fuel pressure tester kit as there was absolutely no need to. In fact, all that I had to do was to open the case, take out the fuel pressure tester, and screw the attached connector onto the fuel rail. Afterwards, I simply turned the ignition key to the ‘ON’ position, and then monitored the pump pressure gauge. Seeing that the fuel pump was delivering 46 PSI, my father’s car obviously didn’t have a fuel problem which was all that I needed to know. What I can tell you was that this must have been a very precision made pump pressure tester as there were no leaks or mess anywhere. It was then a simple matter of activating the pressure release valve on the gauge which conveniently discharged any remaining gas into a small tin can that was lying around nearby. Even then, there was only a trickle of gas that actually made its way into the tin can which quickly evaporated out. So, after disconnecting the fuel pressure tester from the fuel rail, I then reconnected the fuel rail cap. Well, so now you know. This looks like a real winner to me folks!
Worked great! All the adapters it came with are a plus. After almost going crazy trying to figure out why my car wouldn’t start (It was getting fuel, spark, air and the timing was correct). I bought this on a hunch. Using this I found out the fuel injector pressure test kit was there but really low after the fuel pump. Pull the pump out and saw that it had a bad hose in the tank. This product saved my insanity.
Thankfully, I finally got the fuel injector pressure tester kit right on the third try. I used the tester for a ’99 Saturn SL2 which ultimately required an adjustable nozzle adapter to fit on the port. This one sealed successfully, as the adjustable design worked as intended and I could definitively compare where the BlueDriver one failed. The BETOOLL worked perfectly, didn’t leak, and I got a nice, clean PSI reading. You can buy an inexpensive kit, but it has to get the job done. I went with a questionable brand and an untested brand, and those didn’t cut it. So do yourself a favor and invest in this tool, because it will actually get the job done.
8. Shankly Compression Tester (Professional Grade)
Engine compression tester with long flex hose and adapters eliminate the need to remove secondary equipment such as power brakes, steering, air conditioning and manifold components.

With a professional compression gauge, this Cat diesel fuel pressure tester ensures accurate and reliable readings. An ideal tool for compression tester small engine, medium or large engines.
I had originally bought a duramax diesel fuel pressure tester from Harbor Freight and despite their recent changes to better the quality of the products in their store, their compression tester said a chainsaw engine I was working on only had 20% compression. I knew it would be low but even a worn out engine I wouldn’t expect that low unless something was majorly wrong with it. I returned it and bought this one for a whopping 3 dollars more and holy crap… This is a good professional quality one without the professional price. The compression 88% with this one. Alright. That’s a lot more believable and accurate. Definitely recommend this product.
Decent gauge wrapped in cheap but OK rubber. Hoses and attachments seem well made. Using this to diagnose problems with our jet ski. The included hoses, fittings and adapters were all the correct sizes we needed, and all were “O” ring sealed. The diesel engine fuel pressure tester is well laid out and all the included parts all have their own spot in the case. Each piece is securely held in place, so your stuff wont be in a jumbled mess when you open it. For the price, I am very pleased with this kit. Arrived well packed as well.

This direct injection fuel pressure tester helps identify and diagnose low fuel pressure, a faulty fuel pressure regulator, leaking injectors, fuel leaks, and clogged fuel filters
Thought I was facing a $700 plus bill to replace a fuel pressure regulator and/or fuel pump on a 5.7L Vortec with 253,000 miles on it. Vehicle idled smoothly, but did have an occasional strong hesitation. These two conditions are somewhat contradictory so I thought check the fuel pressure as the dealership originally proposed (and they wanted to replace all the injectors). Was I shocked when the turn “key on” consistently showed 63 psi and running 57 psi. With engine off it held the pressure over 55 psi for over 15 minutes, no vacuum leak here. Cleaned the throttle plate/body and immediately saw an improvement per the scanner of the throttle position. Replaced the MAP sensor, cleaned the Mass Air Flow and used two bottles of Chevron Techron fuel system cleaner and my Vortec started running like new. The moral here is for the price and the exceptional quality of the tool you just might save yourself a lot of money. For the price and the quality of the tool, if you are suspicious of a equus 3640 professional fuel injection pressure tester issue you can’t go wrong with the Equus 3640.
For occasional use – this seems like it will do just fine – comes with adapters, hoses, complete instructions, etc. Worth even one time use compared to taking vehicle to shop (or misdiagnosing fuel pump). (I put 5 stars for accuracy, however that’s my guess – basically your pump/pressure regulator are within spec, or not. +/- a pound or two not critical.

FAQs on the Best Fuel Pressure Tester for 2021
What is the fuel pressure tester?
You need the tester to check the fuel pressure as you may not always consider your guesswork because in many cases it cannot be accurate. The wrong reading can sometimes lead to the damaging of your fuel pump by pushing it further. Also, you down not need any expert to check the fuel pressure of your vehicle and you can do it on your own as you do not need to acquire much knowledge about it. Also, you can save your money as you do not have to go to any workshop for the simple measurement of the fuel pressure of your vehicle. When the multiple fittings are connected to your vehicle and
How to use your fuel pressure tester?
The first and foremost step is that you must park your vehicle in a ventilated area for safety purposes as the fuel vapor is more dangerous than the liquid fuel due to its flammable nature and make sure that there you keep a fire extinguisher near you while testing the fuel pressure. The is designed in such a way that it consists of the gauge which is attached to the fuel hose and multiple fittings. Pop the hood when the engine of your vehicle is all cool. Remove the Schrader valve which you can find under a fuel rail or plastic engine cover. Attach the pressure tester for fuel pump with the fitting provided in your vehicle. For a leak-proof fitting, make sure that you have properly threaded. Turn on the ignition and check the reading of the PSI displayed clearly on the gauge. Wait for any PSI drop which indicates the leaking in the fuel system of your vehicle. If the reading remains constant after some time for about 5 – 10 minutes then it does not have any fuel-related problem. Also, you need to understand the low, high, or zero pressure shown in the gauge of your fuel pressure tester.
Why the fuel pressure gets dropped?
The reason behind the dropping of the fuel pressure is the weak pumps, so it is very important to take good care of the pump of your tester. Also, it can be due to the restricted lines, dirty filters and improper tank venting so it is important to check if the pump is in good condition or not. You can easily inspect that your fuel pump is properly working or not as it makes a sound when not in good condition. Also, it can indicate to you by sputtering or coughing that it is not in a good working scenario and there is some problem with it.
What is an average PSI of your fuel pressure tester?
Usually, the average PSI of the fuel pressure tester is considered to be 100- 140 as it a good range of measurement. Also, make sure that the pressure of the fuel system in your car should not be low, zero or high and must be in mild to provide you with high performance. With the low pressure, you may face some severe problems like it may be struggling for you to start your vehicle or stalling, hesitation or backfiring. With the high pressure of your tester, you may face some major issues which are due to the damaged regulator or a clogged fuel line. If the gauge reads the zero pressure, this means that the fuel pump is dead and would not get sufficient power. You must then ensure that the fuse of the fuel pump is in working condition. Make sure that the fuel pump does not deliver the fuel with high, low or zero pressure and understand the reading of the gauge properly.
How to inspect the fuel regulator of your vehicle?
There are many indicators that the regulator of your vehicle would indicate if they are not working properly. It is important to note that they are a very important tool for your pressure tester so you must take good care of it and replace it if it is not working. If there are any misfires, leaks, or black smoke then you must change the regulator. To easily inspect if there is any leak or not, your product must have piston rings, exhaust valves, and head gaskets in the fuel pressure kit. When there is a misfire or decrease in the power, acceleration, and efficiency of fuel, then it indicates the failure of the regulator and will disturb the fuel pressure of the vehicle. Also, due to the fuel leak, the regulator of your vehicle is affected which leads to the emission of black smoke from the tailpipe. And the fuel smell will tell you that the failure of the regulator is due to a fuel leak which may adversely affect the performance of the engine in your car and also reduces the mpg. As the regulator is an essential component of your pressure tester for fuel pump, you must take good care of it and if you find any fault then you must get your vehicle check by the technician near you and get it to replace.
