  Q: How do you remove the fuel pump/fuel level sending unit module on Buick LaCrosse?

  A: To remove the fuel pump/fuel level sensor, 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/fuel level sensor, 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/fuel level sensor locknut counterclockwise. If the locknut is tight, use a hammer and brass punch to loosen it, avoiding steel punches that could produce sparks. Carefully remove the pump assembly, being mindful not to damage the fuel level sensor float arm and float. Before installing the pump, remember to replace the O-ring. The installation process is the reverse of the removal steps.
