To disassemble the fuel pump/fuel level sensor module in 2004 through 2006 G35 Sedans and 2004 G35 Coupes, follow these steps:Carefully disengage the catches to separate the fuel level sensor assembly from the fuel filter/fuel pump assembly. This allows access to the fuel pump electrical connector.Disconnect the fuel pump electrical connector and separate the two assemblies.Remove and discard the old outlet pipe O-ring.

During installation of the fuel pump/fuel level sensor module, it's important to replace the old sensor mounting flange 0-ring with a new one. This step ensures proper sealing and functionality of the module.

If the fuel pressure is lower than the specified value, you should check for a restriction in the fuel system. This restriction is likely caused by a clogged fuel filter or a clogged inlet strainer located at the base of the fuel pump/fuel level sensor module in the left fuel tank.
