Great tester. I went to one of the popular ...
CObuyer•September 27, 2017
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.

looks like pump 3 for me coming up
R. March•May 25, 2017
Bought to use on my 01 GM truck and Tahoe and Yukon. After 16 years the the Yukon's fuel pump failed, borrowed a pressure tester from O'Reilly that left a lot to be desired, noticed the gauge fluctuated when I'd move the hose or gauge. In the same month the Tahoe's fuel pump started acting up and bought this gauge. Lubed the sealing ring and checked all three vehicles. Gauge functioned perfectly. Found the O'Reilly pump I put the the Yukon(precision brand) had 50 psi while idling, and held pressure at 45 when off. The new AC delco pump in the Tahoe read 51 at idle and held 45 when off, but on key on, it primed to 60, leveling off at 55 when primed. My truck, still on factory pump, was holding 49 PS while idling, and bled of rapidly when key off, looks like pump 3 for me coming up...

Not a bad gauge for the price.
J. M. Pridgen•April 22, 2017
Is a good gauge for the price. I managed to test my fuel pressure and it was nice that it came with extra attachments for other vehicles. In retrospect I wish I had only purchased a gauge and no accessories as I didn't need them. I was hoping I could use the T-attachment to tie into the fuel line before my fuel filter but it was unfortunately not the right size for the quick connects on my vehicle. However, it was never advertised for this function.
I do like the long hose and the rubber around the gauge. I was able to read the pressure easily inside my vehicle.
I included a video of the pressure reading on my vehicle before I replaced the fuel pump.
