If it goes back into tank that's not so bad. If the injectors are leaking i would like to know before too much gas gets into oil...same thing for the regulator...i understand the fuel will pool inside the plenum if the regulator is shot.
****i read in another thread that the fuel pressure regulator housing is another area where pressure leak down can happen?? is this true? if so...how does that work?
Thanks

I think the pressure bleed off does matter and i would want to know where the fuel is bleeding off to.

a no start from rich condition is wet plugs. check one of the easy ones to verify BEFORE starting engine, maybe after it spins for a few seconds.
if no fuel on plugs, none in FPR vac line, and engine starts fine one hour after warm -even with pressure at zero- is the pressure part of the root cause?
