PREPARATION STEPS

1. Park the Vehicle:

   • Ensure the truck is on a level surface with the parking brake engaged. The engine should be off and cooled down.

2. Lift the Vehicle (if necessary):

   • If access to the fuel filters requires it, lift the front end with a jack and secure with jack stands.

RELIEVE FUEL SYSTEM PRESSURE

1. Locate the Fuel Pump Fuse/Relay:

   • Check your owner’s manual for its position in the fuse box.

2. Remove the Fuse/Relay:

   • Pull the fuse or relay to disable the fuel pump.

3. Start the Engine and Let It Stall:

   • This relieves pressure in the fuel system. Turn off the ignition once the engine stalls.

4. Reinstall the Fuse/Relay:

   • Place the fuel pump fuse or relay back in its original position.

REMOVING AND INSTALLING THE FUEL FILTERS

1. Locate the Fuel Filters:

   • Primary Fuel Filter (Mopar 68157291AA): Typically near the engine along the fuel line.

   • Secondary Fuel Filter (Mopar 68436631AA): May be further down the fuel line or near the fuel tank.

2. Remove the Old Fuel Filters:

   • Position Rags: Place rags or a container under the filters to catch spilled fuel.

   • Disconnect Fuel Lines: Use a fuel filter wrench to disconnect the lines from the old filters, being prepared for fuel spillage.

   • Remove Filters: Unscrew both the primary and secondary fuel filters.

3. Install the New Fuel Filters:

   • Prepare New Filters: Optionally, pre-fill them with clean diesel fuel.

   • Install Primary Fuel Filter (Mopar 68157291AA): Position and hand-tighten the new filter, ensuring it’s oriented correctly.

   • Install Secondary Fuel Filter (Mopar 68436631AA): Position and hand-tighten the new filter, checking its orientation.

   • Reconnect Fuel Lines: Attach the fuel lines to the new filters and secure them.

4. Check for Leaks:

   • Turn Ignition On: Without starting the engine, turn the key to the "On" position to pressurize the system.

   • Inspect for Leaks: Look around both filters for leaks and ensure all connections are tight.

FINAL STEPS

1. Lower the Vehicle (if lifted):

   • Carefully remove jack stands and lower the vehicle.

2. Start the Engine:

   • Start the engine and let it run for a few minutes, checking for proper operation and leaks.

3. Dispose of Old Filters:

   • Take old filters to a recycling center or an auto parts store that accepts them.

4. Record Maintenance:

   • Document the filter replacement for future reference.
