The fuel pump module comprises the fuel pump, fuel level sender, pressure regulator, and filter. Check part availability before removal as some may not be replaceable individually. In some models, these components are part of the fuel tank assembly, necessitating full tank replacement if faulty. To replace the module, you can relieve the fuel system pressure, remove the rear seat cushion, disconnect the fuel pump wiring, and remove the access cover. Remove the lock ring and lift out the module, ensuring the O-ring doesn't fall into the tank.
