🔥 Holley 26-500 Fuel Pressure Gauge with Mechanical Operation Review

Why buy a controller if you don't have a supply problem. Just buy this sensor that will tell you if your mechanical pump is working well or not. 5 minutes to install, good brand Holley, Holley Duel fuel line with proper thread.

I do not recommend this product. After 2 weeks the sensor started to "jump" so I checked for leaks or problems in the fuel line or pump. Nothing found. After another 2 weeks, the pressure gauge was "cloudy" and then gasoline began to flow out. A very poor product not to mention the fire hazard it can pose if it leaks in a hot engine compartment. This has been used for a new fuel line, new motor, new fuel pump etc. I'm just glad I found it before it caught fire.

I like that I can connect directly to the Holley regulator. Gives me a great view of the gauge to make sure I have the right pressure. The first thing I received was clearly a return as the packaging had been re-taped (see photo). The gauge was upside down so I didn't notice it was reading 2psi when it wasn't even plugged in (see picture). Revain did a great job of sending a new one just had to take it to a returns shop. I didn't know how to use it, so I can't comment on its accuracy. Update: I
