Preparation Steps:

1. Park the Vehicle Safely:
   • Park the truck on a level surface and engage the parking brake.
   • Ensure the engine is off and has cooled down.
2. Lift the Vehicle (if necessary):
   • If you need to access the fuel filters from underneath the vehicle, use a jack to lift the front end and secure it with jack stands.

Relieve Fuel System Pressure:

1. Locate the Fuel Pump Fuse/Relay:
   • Refer to your owner’s manual for the location of the fuel pump fuse or relay in the fuse box.
2. Remove the Fuse/Relay:
   • Pull the fuel pump fuse or relay to disable the fuel pump.
3. Start the Engine and Let It Stall:
   • This will relieve pressure in the fuel system. Turn off the ignition once the engine stalls.
4. Reinstall the Fuse/Relay:
   • Put the fuel pump fuse or relay back into its place.

Removing and Installing the Fuel Filters:

1. Locate the Fuel Filters:

• Primary Fuel Filter (Mopar 68157291AA): Typically located along the fuel line near the engine.
• Secondary Fuel Filter (Mopar 68436631AA): May be located further down the fuel line or closer to the fuel tank.

2. Remove the Old Fuel Filters:

• Position the Rags: Place rags or a small container under the filters to catch any spilled fuel.
• Disconnect the Fuel Lines:
  • Use a fuel filter wrench or appropriate tool to disconnect the fuel lines from the old filters. Be prepared for some fuel spillage.
• Remove the Filters:
  • Use the wrench or appropriate tool to unscrew and remove both the primary and secondary fuel filters from their mounting locations.

3. Install the New Fuel Filters:

• Prepare the New Filters:
  • If applicable, pre-fill the new filters with clean diesel fuel to minimize the time needed for the fuel system to prime.
• Install the Primary Fuel Filter (Mopar 68157291AA):
  • Position the new primary fuel filter in place.
  • Screw it into the mounting bracket by hand. Ensure it is oriented correctly (check for an arrow indicating the fuel flow direction).
• Install the Secondary Fuel Filter (Mopar 68436631AA):
  • Position the new secondary fuel filter in place.
  • Screw it into the mounting bracket by hand. Ensure it is oriented correctly.
• Reconnect the Fuel Lines:
  • Attach the fuel lines to the new filters and tighten them securely.

4. Check for Leaks:

• Turn the Ignition On:
  • Without starting the engine, turn the key to the “On” position to allow the fuel pump to pressurize the system.
• Inspect for Leaks:
  • Check around both new filters for any signs of leakage. Ensure all connections are secure and no fuel is dripping.

Final Steps:

1. Lower the Vehicle (if lifted):
   • Carefully remove the jack stands and lower the vehicle if it was lifted.
2. Start the Engine:
   • Start the engine and let it run for a few minutes. Check for proper operation and ensure there are no leaks.
3. Dispose of Old Filters:
   • Take the old filters to a recycling center or auto parts store that accepts used fuel filters.
4. Record Maintenance:
   • Document the filter replacement for future reference and maintenance tracking.
