Default Evaporative Canistor

I think that is what they call the thing. It is mounted underside of drivers side fender on my 77. My question is it has about a 3/8th line comming out of it and I cant figure out where exactly it should hook up to. I know it dont go to the fuel pump I can only assume it either goes into the carburator or to the intake manifold. I bought this car without any engine so it has been lots of challanges figuring what goes where. Thanks to all you folks soom I should have it up and running then get to do minor body work. Thanks for all the help

I believe that is the vacuum reservoir for your headlight system.

Get a copy of Chiltons Corvette 1963-1982 Repair Manual and the Aim for your vette.Chilton shows your canister (diagram fig.56) in section 4....plus a good write up on operation..

Vent on top of carb is where mine went on my 79 (when I had one). Driver's side corner, above fuel bowl on the original q-jet.

Not on a 77. It's a gas vapor canister. As mentioned above...the factory assembly manual (AIM) is a MUST for any Corvette restorer...
