So I just finished rebuilding the TBI assembly on my 1985 Mustang 5.0 and the nut that screws into the back of the TBI assembly for the return fuel line has split in half. I cannot find replacement lines anywhere since it is the only year of TBI and I do not know what to do. It also seems that someone has deleted the charcoal canister system on my car because I cannot find a charcoal canister anywhere in the engine compartment and I hear a loud thump in the fuel tank after the vehicle has been running a minute or two and then I hear another loud thump in the fuel tank after the vehicle has been shut off for a few minutes. I want to replace the charcoal canister system and need to know how I can get all of the parts needed to replace this system and I need to know how I can get a replacement return line that screws into the back of the TBI assembly or some kind of modification I can do to fix the issue. I know the charcoal canister is available on cj pony parts but I don't know what other parts are needed to completely replace this system. PLEASE HELP ME FIX THESE ISSUES!!!
