Hey Everyone, new member here. I have a 93 5.0 with an AFPR, I just checked my pressure and it was at 60 with vacuum off and plugged. Now I know why exhaust burned my eyes while running! So I adjusted it down to 39 but when I reinstall the vacuum hose the pressure doesn't drop like everyone else says it should? Is this normal on a AFPR or is something else going on? Any suggestions?
