Vacuum Pump
Thnx Del:
I'm working on a Challenger right now that appears to have an aux vac reservoir up by the rad.. Hose from base of carb, to a factory looking cannister with one way valve, (no other tubes, hoses attached) then back up to the br booster..
Seems to me, Ferds used to do a similar thing wayyy back
But it sounds like you got other probs to deal with first..
