Mopar 5096149AA Fuel Pump/Level Module Kit

You can Select Your Vehicle to check if 5096149AA fits your vehicle.

Check the battery, fuel filter, fuel line, hoses, and quick-connect fittings for leaks. Use a fuel pressure gauge to check the fuel pressure. If higher than specified, replace the fuel pressure regulator. If lower, inspect the fuel delivery lines and hoses. Inspect the fuel pump inlet strainer for restrictions. If all components are okay, replace the fuel pump. Check the fuel pump fuse and relay. If the fuse and relay are good but the fuel pump still doesn't operate, inspect the fuel pump circuit.

The fuel level sending unit is secured to the fuel pump housing by a pair of mounting rails on the side of the housing. To remove the sending unit from these two rails you must disengage a pair of locking lugs, located on the underside of the sending unit, that can only be disengaged from the mounting rails by aligning them with the cutouts in the rails. Using an awl or a small screwdriver, carefully lever the lug on the fuel level sending unit toward the area between the two mounting rails until it disengages from the locking lug on the upper rail. Then slide the sending unit to the left until the lugs on the underside of the sending unit are aligned with the cutouts in the mounting rails and lift off the sending unit.

Use a hammer and a BRASS punch to remove the fuel pump lock ring in a counterclockwise direction. Lift the fuel pump and O-ring out of the tank. Clean the sealing area of the tank and install a new O-ring. Inspect the fuel inlet sock filter for damage and contamination, replacing it if necessary. Place the fuel pump in position, install the locking ring, and use a hammer and a BRASS punch to secure it. Finally, install the fuel tank.

Reinstall the assembly and tighten the locknut securely.

Depress the release tab and disconnect the electrical connector from the underside of the fuel pump/fuel pressure regulator/fuel level sending unit assembly. Remove the wedge lock from the electrical connector. Using a special terminal removal tool or a suitable substitute, disengage each terminal from the electrical connector and pull out the wire and terminal from the backside of the connector.

Make alignment marks on the mounting flange and fuel tank for correct realignment during installation.

Replace the fuel pump.

Start by relieving the system fuel pressure and disconnecting the negative battery terminal.

Remove the fuel tank cap and listen for the sound of the in-tank pump when the ignition key is turned to On. If the pump is not heard, check the fuses and then proceed to the following steps. Raise the rear of the vehicle and locate the wire harness to the fuel pump. Unplug the fuel pump electrical connector and use a test light to check for voltage to the pump in the On and Start positions of the key. If there is voltage, replace the pump or trace the wires for any open or short circuit. If the pump still doesn't work, have the vehicle checked by a professional.
