Default fuel pressure dropping quick

I have a quick question for you guys.

I noticed that my fuel pressure (on stock gsr motor) drops down to 0 in 15 minutes to 1/2 hour after I shut my car off. Is this normal? I was told that the fuel pressure doesn't drop as quickly as it is on mine.

check for leaks around the lines and rail. if not, then your injectors are leaking a way to check that is to take out the whole rail with injectors on. koeo and see if fuel leaks from the injectors
