Measureman 1.5" Black Dial, 304 Stainless Steel case, Liquid Filled Fuel Pressure Gauge, 0-100Psi, -3-2-3%, 1/8" NPT Center Back Mount

Looks good and functional.

Una vez recibido el producto lo instale en un regulador holley y no funciono siendo un regulador nuevo, instalamos un gauge de la marca holley y ese si funciono.

I used this to diagnose a fuel starvation issue I thought I had. For weeks, I thought I had “Vapor lock”(look it up) in my 1973 Land Rover. I suspected the gas just evaporated and left the system at high temps. I installed this, in-line, just before the carburetor. It reads 4psi fuel pressure. The line remains pressurized to 4psi even after the stall I was diagnosing. I could stall, and have time to pop the hood and check the pressure. Since it was still pressurized, I could eliminate fuel starvation as the culprit. So simple for less than $10. Great buy.My only grievance is that it doesn’t come with fittings. I had to spend extra for fittings to fit my fuel line. Also, those fittings - extra taps and reducers - bulk out the assembly. So it takes up more space than it needs to. The dial is very compact. But fitting it on a rubber line is cumbersome with the extra plumbing. I think it works better on a steel line, if it directly has the right ends on it. But maybe that’s just in the fittings you find. I couldn’t find the exact one I needed (something like 4 AN-to-5/16” barb) in one fitting…so I had to chain 2 together. But the gauge works great and it’s a good price.

Far superior to most low pressure fuel pressure gauges.

I bought this for an agricultural fire extinguisher that was leaned against a fence at the dump. The gauge on it was all melted… and it is was empty. I installed this new gauge and pressured it up to 90psi and it’s held pressure for a week.
