Hi I have a 1971 Chevelle Malibu. It originally came with an emissions canister but that was disconnected long before I got the car. The original 307 engine has been replaced with a 350 engine with a four barrel carburetor. The car sat up for a long time causing the gas tank to rust. I removed it and ordered a replacement tank and sending unit. The original sending unit did not have a vapor return tube, the new one does. My question is, where do I run the vapor return the canister, to the carburetor? Any help would be greatly appreciated and/or if there is a link to another web site that can answer my question that would be wonderful. Thank you. Confused
