Mike 3898 Posted April 11, 2024 Report Posted April 11, 2024 I have a 1979 m20J. I have had trouble with my fuel pressure gauge. It is intermittent and goes to 0 at times. I have a secondary fuel pressure gauge that shows i have pressure.. Any thoughts or suggestions? I am also having trouble finding a new instrument... Thanks Quote
