fuel pressure unknown pump Checked my fuel pressure today and it's at 65 when running and drops to about 55 when I hit the accelerator. No clue what pump car has in it but it has been changed. How much pressure should it have at idle? Al.so it does not hold pressure when car is shut off.

I have the same question as far as I know mine is stock and it also loses pressure as soon as shut off. Also like your it drops when you give it gas. My car stumbles/ bucks and crusing speed when you hit accelerator I am wondering if the pump is bad or going bad?
