Review on 💨 Innova 3620 Vacuum/Carburetor Fuel Pressure Tester: Ultimate Diagnostic Tool for Efficient Engine Performance by Scott Reid

Build quality is reasonable but not essential but I expected it so I'm happy. I got it to check the vacuum line going to the secondary air valve that was triggering the check engine light. I was able to verify that a vacuum was present, eventually diagnosing that the valve was defective. It was a frugal purchase that did the trick. If I had to use a pressure gauge like this more often in the shop, I might choose something more durable. But for my purposes it did a commendable job and I'm sure it will continue to be used in the future.
