What is a normal pressure reading for a Walbro 255? The reason Im asking is because Im about to install a SFMU and I dont know guage I should get with what pressure limit. Im looking at an Autometer with a fuel pressure limit of 100PSI. Is that too high?? Thanx

Are you running stock injectors? If so then you might want to find a gauge that reads over 100 psi.

The fuel pressure is entirely determined by the fuel pressure regulator (stock FPR or S-FMU). Your maximum boost and fuel injector size will determine what your maximum fuel pressure should be. I'd just buy the 100 psi model. That will be fine for low boost on stock injectors (or higher boost on bigger injectors).
