Fuel pressure with motor off

[TheDoughboy]

How long should the fuel system hold pressure after shutting the engine off? What should be done if it does not "hold it" long enough?

I don't think there is any set time for the system to hold pressure.

The longer it does the better, mine will hold pressure for a couple of hours or longer if I have to work on it hehehe.

If your system don't you either could have a leaky injector, or regulator or even the check valve at the pump is going.
