The gauge that comes with this set is not the best quality. I had to replace the hose because when the ends were crimped on the hose it collapsed the hose. I replaced it with a much better quality hose and while replacing it the plastic face of the gauge cracked. I had to empty all of the liquid out of the gauge to keep it from making a mess in the case. The compression adapters are pretty good quality. The ones that I’ve used have done the job. Other than the quality of the gauge I recommend this set.

Glow plug hole adapter and the pressure gauge fitting does not work together when on the motor. Compression gauge will not hold pressure, it leaks. This is for a 97 Ford F350 7.3 diesel engine.

Useless. Came with no check valve. Will not hold pressure. Looks like a nice kit but does not work.

If you use this on a power stroke ford you will need to build an adapter to clear injector and rocker. M10x1.0 threads use a brake line adapter to make it work takes a little smarts but well worth the time.

Compared to Snap-Off, these were only about 5-10PSI off of what my buddies snap-off gauges were reading.

Bought this to do a compression test on a 98 VW Jetta TDI. Out of the box it is not compatible (that’s ok, I wasn’t expecting it to be) since it has clearance issues with the injectors. None of the adapters provided gave me the clearance I needed – the female quick-connect needed to be a bit smaller or the adapter that threaded into the head needed to be longer. This is not the reason for my review though, that’s more so to help the TDI folks. With that being said, this tester, while “rated” to 1000psi, it does NOT give an accurate pressure reading. And this is due to the quick connect fitting with the kit. When I did my test out of the box on Cyl 1 (the only cylinder I did have clearance for), I got a reading of 300psi. Since I needed to get readings for the other cylinders, I ended up making my own adapter that threaded directly into into the head, and into the gage with no other fittings/plumbing… the same cylinder came back at 420psi. The difference between 300psi and 420psi is the difference between a major issue in the cylinder and tip-top compression within spec. The whole point of the compression tester was to do diagnosis and this thing failed to perform it’s primary function. Both the 300psi and 420psi readings were done on a cold engine and “dry” cylinders so no variables differed between the two either. If you’re looking for a setup that covers the cars in the description this tester *might* still be worth it, but expect to get bad numbers regardless since all the adapters use the quick connect fittings. If you’re scouring the internet for a decent DIESEL compression tester (I struggled finding anything decent), then save yourself the money and get yourself a good liquid filled gage (even the one in this kit is real good), and plumb the adapters you need yourself. 9 times out of 10 you only need one or two anyways. First impressions out of the box were good because the adapters were abundant and the liquid filled gage was good too. BUT, it just didn’t work. Hope this helps someone.

This product did not have the adapter required for my application. It states that it works on Cummins 5.9 engines. It doesn’t work on vp44 equipped engines. It would require adapter TU-15-26, another $60. If you have a guage already, just buy the one adapter. Looked like a good kit, but lacking the one I needed.

Glow plug adaptor did not fit 1999 Ford 7.3 powerstroke directly, needed to use an m10x1.0 grease whip. Might fit older IDI, but not this one…with what came with it.
