Fuel Breather/Canister?
On the drivers side of my gas tank (74) i have a line that leaves a black box runs to a canister in the front of the car and then returns. What is this for? Is it necessary? A good idea? I'm currently replacing all my lines and so i'm trying to determine what to do with these.
Thanks,
Thomas

Re: Fuel Breather/Canister? (tzavaleta)
my 71 has the same thing. It is a charcoal canister through which the tank vents its fumes through especially on hot days. Mine is still hooked up to the tank but not to the carb. This way the tank can vent and release pressure but the charcoal canister will eventually become saturated and no longer perform its job evaporative emissions controll. The reason I didnt hook it up was because I switched my carb among other things so I no longer had the vaccume hookup. The canaster must be hooked up to a switched system so it only recieves vacume at certain throtle positions. Otherwise you would essentially have a vacume leak in your intake instead of the canaster being periodically cleared of vapors. :mad :mad
