Mounted on the holly fuel pressure regulator this allows me to see my exact fuel pressure on my hot rod.With out it you are gussing and run the risk of fuel starvation of overflowing the carb. The liquid fill keeps the needle steady. Note the gauge I received has a white face not black as in the photo.

Why buy a regulator if you don't have a feed problem. Just buy this gauge, tells you your mechanical pump is working well or not. 5 minutes to install, good Holley brand that was correctly threaded for Holley duel fuel line.

Love that I can connect directly to Holley regulator. Gives me great sight of gauge for making sure I’m at the right pressure.The first one I received was clearly a return as the package was re- taped together (see pics). The gauge was turned around so I didn’t notice it was at 2 psi when not even hooked up (see pic).Amazon was great at reshipping a new one, just had to drop off at a return store.As a result I haven’t been able to use, so I can’t comment on accuracy.Update: in order to connect to regulator I had to buy a reducer.

I can't recommend this product. After 2 weeks the gauge began "bouncing" so I checked for leaks or problems in the fuel line or pump. Nothing found. After another 2 weeks, the gauge "clouded up" and then began pouring gas out of it. A very poor product not to mention the fire hazard it can cause when it starts to leak in a hot engine compartment. This was used on a new fuel line, new motor, new fuel pump, etc. I'm just glad I found it before it caught fire.

Gauge is accurate. Lens fell off easily, re-installed and it appears it "snapped" back on, hopefully it will stay. Package was open inside a sealed/padded envelope, but the 90 degree fitting was missing. Would have given higher rating if not for this.
