Marshall Instruments LB00015 Liquid Filled Fuel Pressure Gauge

Great gauge that works well. I like that it's fluid filled. Put it on a holley return style regulator.

it has been working fine for at least 6 months at this current time of writing this review. I recommend a good fule pressure guage on all diesel vehicles.

Everything seems to be as advertised. Very fast delivery

I bought this Guage to replace the bouncy not so accurate Holley Guage that I had been running for about 7 years. It was easy to install, smooth needle operation, accurate, was very happy with it! I had the Guage on my 64 corvette with 4 barrel Holley carb just a few weeks shy of a year with not even a gas tanks worth of driving. Anyway, I was sitting in my garage waiting for the car to warm up when I realized there was a huge puddle forming under the car, yes it was gasoline, alot of gasoline. Turned the car off, opened the hood, everything was soaked, even the battery. What a horrifying mess! I'm not sure what caused the Guage to fail but I'm damn lucky everything didn't go up in flames. I have since installed a plug and no leaks, I think I can live without a Guage. I don't discourage using this Guage, but be careful.

High quality gauge, after purging the case for my altitude and current temp it is very accurate and steady even though I haven't installed a snubber between it and my 93 cummins diesel. Very nice manual gauge for the money.

Nothing else to say, it looks great and does what it is supposed to do, regulate fuel pressure.

Item received was as advertised...Buy with confidence!
