fass ddrp lift pump pressure.
 

Ok what to do i have a FASS DDRP LIFT PUMP and whenever my truck warms up and expecially when hot my lift pump starts pushing 25 psi whenever i pull a heavy trailer for a good ways and then stop at idle it will max my gauge out to 30 psi im not for sure if my gauge is right but maybe?

didn't you have this on a post a month or so ago? find a shop that can test the pressure for you and see if your gauge is correct.
