• If the truck has a skid plate, remove it first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure and disconnect the battery

• Use a 10mm socket to disconnect the negative battery cable.
• Relieve fuel pressure following the truck's fuel system service procedure before opening any line.
• Fuel spray is the main risk here.

Step 2: Raise and support the truck

• Use a floor jack to raise the rear of the truck.
• Place jack stands under the frame rails and lower the truck onto them.
• Keep the truck stable before going underneath.

Step 3: Disconnect the fuel tank filler and vent connections

• Use a flat-blade screwdriver and trim clip removal tool to remove any shields or retainers blocking access.
• Loosen the filler neck and vent tube connections as needed.
• Set the hoses aside so they do not tear when the tank is lowered.

Step 4: Disconnect electrical and fuel lines

• Use a fuel line disconnect tool set to release the quick-connect fuel lines.
• Unplug the fuel pump electrical connector.
• Inspect the connector and line ends for dirt before opening the system.

Step 5: Support and lower the fuel tank

• Use a floor jack with a wide support surface to hold the tank.
• Remove the tank strap bolts with a 13mm socket.
• Lower the tank slowly and watch for any remaining hose or wire attachment.
• Go slow and check every side.

Step 6: Remove the fuel pump module

• Clean the top of the tank with compressed air or a clean rag before opening it.
• Use a screwdriver or the proper lock ring tool to remove the pump retaining ring.
• Lift the fuel pump module straight out of the tank.
• Remove the old seal from the tank opening.

Step 7: Install the new fuel pump module

• Install the new seal in the tank opening.
• Lower the new fuel pump module into place carefully so the float and pickup do not bind.
• Install and tighten the retaining ring securely.
• Make sure the module sits fully seated before moving on.

Step 8: Reinstall the tank

• Raise the tank with the floor jack while guiding the hoses and wiring.
• Reconnect the fuel lines and electrical connector.
• Reattach the filler neck and vent connections.
• Reinstall the tank straps and tighten the bolts. Torque to 40 Nm (30 ft-lbs)

Step 9: Reconnect the battery and prime the system

• Reconnect the negative battery cable with a 10mm socket.
• Turn the key to ON for 5 seconds, then OFF. Repeat 3 times to prime the system.
• Check under the truck for any fuel leaks.

Step 10: Start and verify operation

• Start the engine and let it idle.
• Check for leaks around the tank, fuel lines, and filler connections.
• Listen for abnormal pump noise.
