I need some advice. I just installed my adjustable fuel pres. reg. and bump up the fuel pres. from 43psi to 55psi and the car has a little trouble starting. I am thinking it might be the fuel pump have any of you had problems before. help me out. other than that to the car runs smoother and no more backfires and it responds to the gas pedal a lot better.
thanks
Luis
