I need a fuel pressure gauge for my regulated return . The gauge is under the hood and its like 1 3/4" or maybe 2" and its liquid filled 0-100 psi. The gauge is not illuminated. I dont know what brand the one I have is but its a big pos. I dont think its working properly. I had the pressure set at around 60 PSI and its reading 42 and when I crank the adjustment around it doesnt increase or decrease the pressure(according to the gauge). I would like to have a better branded one that I can trust.
