0-15 Psi Fuel Pressure Gauge, 1-1/2" Black Dial, 1/8" NPT Back Mount, Silicone Oil Liquid Filled, Stainless Steel Case, Inline Low Pressure Gauge, for Water Oil Pressure Test

Works as it should, oil filled is nice with vibration!

Works well with application.

Why did you pick this product vs others?:I need a 0 to 15 psi, everything else was 0 to 100+

Item looks good, haven't used it yet.

This pressure gauge is very nice and accurate i used it on my edelbrock carburetor fuel line

It seems accurate as it matches the digital readout on the dash.

I used this for an Edelbrock 4bbl setup on a 78 Ford 400. The stock mechanical fuel pump is said to produce around 7 lbs. of pressure whereas the Edelbrock carbs will only handle 5-6 lbs. or they leak. I had installed an adjustable fuel pressure regulator ( a knockoff of the Holley version, mounted on the fender well) that was said to be factory set to 6.5 lbs. I adjusted it down after installation but was only guessing. Sure enough, the carb leaked.We kept adjusting the regulator until it stopped leaking but had no idea exactly how much pressure the carb was getting. I had already installed the Edelbrock 90* fuel inlet adapter to the carb so the fuel line would feed in from the front & it has a fitting built into it for just this purpose. I decided to put a gauge on it out of curiosity & this unit was inexpensive & had gotten decent reviews. It fits well in this application & hasn't leaked after a few weeks of use. Turns out the carb is getting just a tad under 5 lbs. of pressure per this gauge. I haven't compared it to any professional/high end gauge so take that with a grain of salt.

DO NOT BUY THIS! Once this gauge gets to operating temperature it goes to 0. I used a test gauge to measure fuel pressure and it showed 6psi when this crappy gauge showed 0. It will have you chasing your tail. Horrible!
