Hello..I have a B&M Fuel Pressure gauge installed on my fuel filter..When the car is running, I get about 42psi. Problem is, once I turn the car off, the pressure will go down(not right away) to about 20psi and stays there for days and doesnt bleed off at all..I have a stock FPR. What can be the problem, since I know the pressure should be 0 with the car off, sitting for a while..

 

i'm not sure i'm seeing a problem.

 

Before, the pressure would releive in like lets say an hour,and will go down to 0..
But now,it relieves pressure but stays at 20psi,
so IDK if its normal for the fuel system to still hold the pressure,even after 3days..
So I just found it weird

 

its fine.

 

no problem. no leaks and starts fine, no issue.

 

Thanks for the quick inputs fellas..And no leaks,starts up, but not right away since Im turbo and the motor is running rich *** hell..10.0 on A/F gauge
