How long should the fuel system stay pressurized after the engine is shut off?

On my 97 LS all OEM fuel components the fuel pressure only holds for 1-2hours on the fuel filter mounted pressure gauge. I have a rough(misfire) idle on semi cold startups and think its a leaky injector. NO CELS and #1 cylinder plug looks slighty rich compared to the other 3. I have moved the #1 injector over to #2 and will recheck the plug in a few days.

up

 

I forgot to look it up... But a couple hours sounds OK. The Helm book says something like xx psi allowable in 30(?) minutes or something like that.

what section of the helms?

 

Fuel supply system? I'm pretty sure I've seen it somewhere in there. Look in the section where you test the FPR.

 

It mentions nothing about holding fuel pressure. Its a 96 manual for 96 and 97.

 

Then I'm probably confused about where I've seen it.
I looked in my '98/'99 Accord Helm book & didn't see it. But still, if it takes a couple hours for the pressure to drop, that sounds OK.
