Update! Replaced fuel pump actuator and passed fuel leak test only lost 3,400 psi in 1 min. Thanks starlight!!!

You have something else doing bad in fuel system. Pressure on my engine stays almost same for hours.

It goes from 29,100 to 25,600 and stays there doesn't drop after 1 min. It shouldn't drop at all? What else can be wrong?

If it stays it's OK. Was thinking it dropping down every minute. The dropping pressure depends on on temperature to. If it;s cold outside the fuel cools down more rapidly.
