Thread: How to check fuel pressure

    Default How to check fuel pressure

    How do you check the fuel pressure on an M20 engine? I know with a gauge, but is there a port to check from or do I tap into the fuel line? If so where does the fuel enter the manifold? I need to test tonight so any quick help is greatly appreciated.

    you have to tap into the hose with a T-piece in such a pressure testing set, between the hose and the fuel pressure regulator.
