To remove the fuel pump/fuel level sending unit module, start by relieving the system fuel pressure and equalizing tank pressure by removing the fuel filler cap. Then, disconnect the cable from the negative battery terminal and proceed to remove the
Fuel Tank. Next, disconnect the electrical connector, fuel supply line, and EVAP hoses from the fuel pump/module, making sure to soak up any spilled fuel with a shop rag. Mark the orientation of the fuel pump in relation to the fuel tank for proper realignment during installation. Using large water pump pliers, unscrew the fuel pump/module lock ring by turning it counter-clockwise. If the lock ring is tight, use a hammer and brass punch to loosen it, avoiding steel punches that could produce sparks. Remove the lock ring from the tank and carefully remove the pump assembly, being cautious not to damage the fuel level sensor float arm and float. For installation, replace the O-ring before installing the pump and follow the reverse steps of removal.
