F/P QUESTION???

Ok, @ idle i have about 25lbs. with vacuum line on...38-39lbs. with vac line off...is this correct?? And when the engine is off should fuel pressure stay? or does it purge after awhile??

39# with vac line off is right, but 25# with vac line off sounds a tad low. Possible vac leak somewhere in the system?

I've searched for that issue but found no leaks...wonder if fuel filter could be the prob. After searching the forums it sounds like maybe that could be the culprit.
