I agree with the FASS idea

you cannot change your pmw as far as i know.

your lp pressures should not drop to 0 like i said from what i have been told the raptors are not holding up

 

New..!! up date, As I told you before I replaced everything before the pump. got into it with a raptor tech. telling me it could not be there pump. so I talked to the management. He was a lot more willing to try and help. thinking about it I decided to take everything off after the pump. the techs where certain it would not be there. WELL IT WAS. I don't know what or where it was but it was.

with it all behind its all good know,
and it was not there pump...

 

Interesting and congrats on getting the problem worked out.
