Charcoal Canister..............

Working on a 70's Dart with A/C and a 318......... The owner would like to keep the engine bay as original..........BUT, the 318 has already been worked over a bit with a 4 BBL. setup, SO it's not really too original already.....

I'm not dead sure about the original "charcoal canister" system..... Has a hook-up for the gas tank, which if I remember correctly, acted as a vent of sorts on these models when the vacuum lines were all still hooked up....BUT, not sure whether it serves a purpose other than simple air filtration of sorts when you get down to brass tacks........

Would any of you guys opt to hook up all of the lines as it was originally (Carb Vacuum, PVC, Gas Tank, and Distributor Vacuum), OR just scrap it altogether?........and if it's scrapped, what about the line from the gas tank?

How about a little input............. Seems like a waste of good vacuum to me, with little benefit.........This is not a 100 point show car......just a cruiser.

Thanks guys.............. Doc
