Thanks for all your help. Sorry, I got caught in all the Huntington Beach protest mess about beach closures but am home now. Yes you are right the car does have an Aeromotive FPR. I am not sure if this one in the link below is the one I have (or may need) but for illustration it does show what the small vacuum connector looks like. So it looks like I should be able to slide the hose off without damage and test at the FPR metal line and/or at the hose/engine line. I have a hand vacuum pump as shown but can't find my instructions or even youtube or google for use on the FPR. But I am thinking if I attach it to the FPR with the engine off and pump the vacuum pump to lets say 10 or 20, then shouldn't the pump hold that same pressure? If it would drop maybe the diaphragm may have gone bad? I like the suggestions to drive the car hard too, but if the FPR is bad I am thinking it may be putting small amounts of gas in the engine which may not be good. Thus trying to test the FPR first.
