Pump Connection
When replacing the FDM, the pump inside it, or just the reservoir head, the original wires CAN be connected to the new pump without cutting. But if the wires are soldered or crimped properly, this is a secure connection. The splices do NOT need to be sealed, and attempting to do so using sealants, glues, or other chemicals may contaminate the fuel. Gas doesn't conduct electricity, and also flows through the electric pump motor anyway, so just prevent the metal wires from touching each other or the metal tubes.
