boost/vac guage reading

[fasteclipse1992]

idling my boost/vac guage reads around 15-20 vacume pressure and at boost 9 . is that normal reading on the vacume side?

No, you're short on the vacuum side. Where are you tapped in?

im tapped in that fuel pressure thingamabob on the firewall above the power brake booster. i had an idle sure and the reading wasnt accurate at the time. i fixed that problem now it reads 17-18 on the vacume side
