I don't have a pick yet. The part in question is the little canister that is located just in front of the fuel distributer, with fuel lines running to it, then to one of the ports on the FD. There is also a little vac lin that runs into it from the engine side. What does this do? I as because upon disconeccting the vac line that runs to it, I lost the connector. I made due with what I had, and just used a vac butt conecctor, but I'm not sure that the conection is tight enough. Please advise, thanks!
