Anyone taken their hpfp out only to return it in and have it squeal at idle? once the car demands fuel pressure the noise goes away. has anyone had this or fixed it? Maybe it is a problem to the injector rail i am not sure.

Squealing hpfp? I never heard of that. Maybe a squealing lpfp though.

Matt O figured out what it was with John Powell. It is a pcv blockage which is causing the rocker cover cap seal to vibrate because it can't seal the pressure due to the blockage. In a friends car with the same noice his was fixed, mien is either a blockage in teh pcv line from the intake or another one.
