Perhaps you need the fitting on that screws into the top of the pump to attach the main fuel line to. You old fuel pump you sold me still had this on it and I did not know what to do with it as it looked different from the fitting I have. Perhaps you need this part back. If nobody else has any suggestions, let me know and I'll mail it back to you. (ultra'at'isd.net) Jim Reeve #6960 [long quote removed by moderator]
