Hooking Up A Fuel Pressure Guage


Recommended Posts

This may seem like a dumb question, but where does the air that is in the fuel rail and pressure guage line go. I could bleed the line at the fitting, but I don't know if I could get rid of all the air or even if I have to. Does the air just go back to the tank through the fuel pressure regulator and return line, or does it escape through the injectors? I just don't want to damage anything testing my fuel pump pressure while I drive. My guage and line setup doesn't have a bleed valve. :unsure:
