Yea it takes a ground down very very thin socket and don't take to tight for it will break new seat. I think now you are not signaling pump to come up to pressure when requisting a lift of header. This requires the number one valve to energize. Check to see if you get magnatism on stud that holds coil on when requisting a lift. If this is good I would suspect master will have to come back off. I believe you will find a problem with check valve or the orfice inbetween sections. Right now you are stroking the pump with signal from steering and you need to stroke it with signal from electric coil. Maybe the master valve you put on was missing the orfice or it is floating loose in there. Good luck
