Thanks Yapper. I was thinking that was the return fuel line after I made the post. I don't really remember exactly how the procedure went but he did shut off the fuel pump then filled the cannister with cleaner, then disconnected both fuel and return lines. With an adapter, he connected the canister into the fuel line, then we started the car and let her run for about 20 min until she died. I think your right in saying that he did it right. Thanks, John
