Used a liquid filled Hooley pressure gauge. Failed when fluid heated up in gauge and gave false reading. Holley Tech Rep said.."we have problems with them gauges when they get over heated"..yah think..they are install on performance racing engines..the get hot! Not made for the grocery getter.Got a gauge without fluid. Gauge read 2.5 psi pressure static..not installed...not adjustable. Installed it any, thinking it might self-correct....nope. Sent it back too.Ordered the third gauge...it read "0" psi..., good...it works perfectly..but tested positive for Covid-19...made in China.

Worked out of the package once, then wouldn't read past 5. It is priced as a quality Made in USA gauge with a reputable name , but is made in China.... and its proven to be of China quality! Just cannot by known name brands anymore without ending up with trash.Shame on Holly!

A well made gauge for showing engine vacuum. Has "Holley" written on the face. Looks good mounted on a roll cage. Works like a charm.

I had to return the vacuum gauge it did not work right. It is sad that holley has to make this gauge in china. I wish they would make their stuff in america,. I would pay more if it was.

I think that it is even made in America, too. Ten words more are required to post a review here,

This gauge is the perfect tool to see what is really going on inside your motor. If you are using a holley carb, this is the ONLY way to see what power valve your vehicle requires. Undampened gauge lets you see exactly what is happening, works great.
