Found this on the H.A.M.B site
vent line should be 1/4" , and have atleast two large 3" loops in it the loops helps prevent the vapors from coming out as they are heavy and settle in the bottom of it . you can install a electric valve in the vapor line that opens when the ignition is keyed on ( did this for one car ) its a tank switching valve from a chevy 78 k 20 truck it has no vent option as its non emissions ( exempt for time ) also have done vapor canisters from late model vehicles as they are smaller and cheaper new . 4th gen impala works good .

On Canister, they still call for a vent line to tank? don't they? If not... What should I look for? 70's Impala Charcoal Canister??
