My fuel pressure will not drop for about 20-30 minutes after turning off car then it goes to zero in a few minutes. Is this typical?

Yes. For a stock setup it's typical.

My stock system will hold some pressure for more than 24 hours. I wonder whose is typical.

FP going to zero after about 30 minutes is normal but the time can vary.
