How long does the fuel system hold pressure?

How long does your car sit (not running) before your fuel pressure hits zero? I am just curious if anyone knows what is normal for the S197..?

Yep I'd say about 20-30 minutes my gauge is 0.

If they play, I spray.

Depends a lot on temperature but I'd say no more than a half-hour.
