My 3000psi flatline leaks out the front adjustment nut once my output increases past 900/950psi. I've taken it apart and replaced and lubed the oring...the seat oring I think it's called, and it's fine and can adjust up to 1000psi output...exactly where I want it! When I go to gas up again a couple days later, it leaks again...any ideas why it would be doing this? Do I need to adjust and bring up the output pressure gradually when I first gas up?
