Best Fuel Pressure gauge?
Looking for input on the best 1 1/2 fuel rail/Regulator fuel pressure gauge? Brand and liquid filled vs standard. I have tried a few in the past and they were never very accurate when engine bay temps got warm and also didn't last long.
Thanks in advance

Kevin, I can't say whose is best but I can tell you that you don't want a liquid/glycerin filled gauge.
That said, my advice is to remove the gauge after the fuel pressure is set.

Re: Best Fuel Pressure gauge?
You want the stepper motor ones. Deadly accurate. They make them in 60-210 Water Temp also. This is a AutoMeter 4463-SP 0-100 . The also have 0-15 also. I have one (0-15) laying downstairs if that's what you need.

Thats interesting. I have found the liquid filled gauges to be accurate. At the instruction of Aeromotive i pull the rubber plug out of the gauge to equalize the pressure. We just installed a Race Pack and the reading on the gauge and the data logger were the same.

All that tells me is it’s not accurate.

Re: Best Fuel Pressure gauge?
I have heard the liquid filled gauge can change as the engine compartment gets hot the fluid changes viscosity. Thanks Jeff for the input also but I am only looking for small rail mounted unit. I just want to have a look at the fuel rail periodically. I have a 2 1/2 gauge with 3 ft hose to verify if I think there is a problem.
