I'm trying to "re-commission" the heater and AC on a 69 Skylark I recently purchased. Rochester was replaced with a 4barrel Eldelbrock and the vacuum line to the vacuum supply canister was thrown away. But the vacuum supply canister inlet nipple was capped. I need to buy both a fitting out of the carb for vacuum source and vacuum line from it, to the Vacuum Supply Canister. It looks like it is 1/8" I.D. vacuum hose, but from pictures I'm looking at (which are all OD) the vacuum lines seem larger than the other vacuum lines. Plus, the nipple inlet on supply canister is larger than the outlet. Does anyone know the proper I.D. for the vacuum supply line from carb to canister? Thanks
