Overall Assessment

Customers appreciate the product for its reliability and functionality. Its key features include accurate fuel pressure reading, good thread engagement, and leak-free operation. The clarity of numerals and easy-to-read face is praised, making mount set up a low cost task. Customers used it to effectively regulate and monitor fuel pressure as well as to diagnose engine issues. One user noted a temporary discrepancy, but it self-corrected. It outperforms in comparison, proving to be a valuable tool in engine compartments for its practical and time-saving operation.

Works great... Helpful diagnostics

I was having problems with a new 600 holley that has non-adjustable floats... requires 4-6 psi max and my fuel pump was putting out about 12. Worked great getting fuel pressure to proper amount by using the gauge and an external fuel pressure regulator...

Not great but works

I installed this on a new regulator I bought from Speedway at the same time. It worked fine the first time but when I fired the engine up the second time the gauge read about 12 lbs. instead of 4 lbs. where I had the regulator set. I had to tap the gauge with a screwdriver about 10 times before the reading started coming down. I shut the engine off and waited about 10 minutes and fired it up again. It read 4 lbs. and worked okay after that.

I give it 5 stars because it's exactly what it says it is. It reads correctly - verified with another gauge and fits well with good thread engagement and no leaks.
