Removal & Installation



These models have 2 fuel tanks (right and left). The fuel pump is part of the fuel sender assembly in the left fuel tank. The right fuel tank contains a fuel sender assembly with a siphon jet pump which supplies fuel to the left tank through the fuel sender feed pipe. Although there are 2 sending units, the removal and installation procedure is the same for both.
