i have a fuel pressure gage , its a sport-comp and what i was wandering is when the car is off should the needle go to zero or should it stay at lets say 35lbs , which is where it is all the time now and doesnt move . I have a P1sc supercharger and it was reading around 50-55 then all of a sudden its reading 35lbs . I did put in a new battery about 2 weeks ago . Im trying to figure out if i have a gage problem or fuel pump problem ???? the needle doesnt move at all on 35 but it use to move back and forth on 50 -55 depending if i was getting on it or not ..
