Did its job!!!
Did its job and found the leaking air caused by a pin hole air leak that was only audible when boost psi got to 40lbs.

david boots –
great product everything worked how it should
great product everything worked how it should. The only issue i had was the packaging everything was packed in a box loosely so the glass cover on the pressure gauge came out from being knocked around.

Can’t do without it
I maintain a fleet of school buses and this tester is used weekly. It has saved us a ton of money in air coolers that otherwise would have been changed for no reason. It is a great addition to the shops diagnostic tools. I bought ours off Amazon because of the price. It came without a case but for the price I can’t complain.

Works well, but ‘quick connects’ leak.
This tester works very well, but only after you take the ‘quick-connect’ end off the cap that has it, and put gas-line thread tape on the threads, then re-install it. I also had to disassemble the gauge unit, reversing the safety plug with the quick-connect plug, so that i could install the unit and monitor the pressure via the intake side of the engine. Tested my Prostar with ISX Engine, and after 20 minutes at 30PSI with air supply switched off, I only lost about 1psi after the mods I had to make to the unit.
