Q: How to Replace the Left and Right Fuel Level Sensor, Fuel Pressure Regulator,Fuel Pump and Fuel Filter Module on Dodge Challenger?
A: To replace the left fuel level sensor and fuel pump module, start by removing the module and cutting the wiring harness clip. Loosen the two retaining clips and pull out the sensor. For the right fuel level sensor, fuel pressure regulator, and fuel filter module, remove the module and disconnect the sensor.
Q: How Do You Remove the Fuel Pump/Fuel Level Sensor/Fuel Filter?
A: A fuel pump/fuel level sensor module, also known as the main fuel pump module, is located in the left compartment of the fuel tank. It includes the fuel pump inlet strainer, pump, fuel level sensor, and Fuel Pressure Regulator. The module is removed as a complete assembly, and most replacement modules come with all these components. The auxiliary fuel pump module is located in the right side of the fuel tank and includes the main fuel filter and fuel pressure regulator. On earlier models, the fuel pressure regulator can be replaced separately, but on later models, neither component can be replaced separately. To remove the fuel pump/fuel level sensor module, the fuel system pressure must be relieved, the negative battery terminal cable must be disconnected, and the fuel tank must be drained to under 5/8-full. The rear seat cushion is removed, and the foam pad covering the module is pulled back. The plastic access cover is carefully lifted off, and the electrical connector is disconnected. The area surrounding the mounting flange is cleaned, and the lock-ring is loosened and unscrewed. The module is lifted up, and the electrical connectors and fuel supply line fitting are disconnected. The residual fuel is drained, and the module is carefully removed from the fuel tank. The installation is the reverse of removal, and after installation, the fuel system is primed by turning the ignition switch to On without operating the starter.
