Important: The fuel pump strainer must be in a horizontal position when the sending unit is installed in the tank. When installing the sending unit, assure that the fuel pump strainer does not block full travel of the float arm.

1.Install the sending unit and a NEW rubber seal. Align the alignment tab to the correct location on the fuel tank.
