Jeep 68051899AA Fuel Pump Module/Level Unit

Inspect the pump inlet strainer for cleanliness and any damage, cleaning it if necessary. Verify that the rubber O-ring groove is clean, and replace the O-ring if damaged. On AWD models, reconnect the internal fuel line to the bottom of the module, then carefully reinstall the module into the tank with proper positioning and the locating lug seated. Finally, align the marks and securely tighten the fuel pump module lock ring during installation. If the special tool is unavailable, alternative locking methods can be used.

Caution must be exercised when working with gasoline, as it is highly flammable.

To begin the removal process, relieve the fuel system pressure and disconnect the battery's negative terminal. Then, disconnect the electrical connector and fuel delivery line quick-connect fitting from the primary module. Before removing the primary fuel pump module, cap the module fuel line fitting and create alignment marks on the assembly and fuel tank for correct realignment during reinstallation. Use a special service tool or a brass drift to loosen the lock ring securing the fuel pump module and lift the assembly carefully from the fuel tank, ensuring the float arm of the fuel level sending unit and fuel pump inlet strainer remain undamaged. Be prepared for fuel spillage from the reservoir when removing the module.
