before autumn fuel tank inspect wiring and also plug/socket under the bottom the the car, periodically terminals burn there.
ok,will execute defsending unit functions fine, but that is ~ above a different wire. However does the come native the very same socket/plug as the pump wires?
sending unit or level sensor share the very same square form 4 wires socket v the fuel pump engine +ve 12 volts and ground.
