after a few hours have passed yea it will bleed down a little bit. is it at zero completely? can you specify how long?

my check valve went bad in my Fuel pump and the fuel pressure would bleed down to zero in about a minute after turning off the motor.

also is it normal for the fuel pressure to rise after i turn the car off. i watched it this time and it rose from 27 to 30.5 in a matter of secs

Edit: alright 20 min have passed since i first posted this and its at 23 psi. so from 30.5 to 23 psi in 20 min. is this normal?
