🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Use the fuel system relay or fuse method, then crank the engine briefly until it stalls if needed.
• Disconnect the negative battery terminal with a 10mm socket.
• Remove the fuel cap carefully to release any tank pressure.

Step 2: Raise and support the truck

• Use a floor jack rated 3-ton minimum to raise the rear if needed.
• Place the truck securely on jack stands.
• Make sure the truck is stable before crawling underneath.

Step 3: Remove tank shielding and access hardware

• Use a 10mm socket, 12mm socket, or 14mm socket to remove any skid plate or shields covering the fuel tank.
• Keep track of bolt locations. Some fasteners may differ in length.

Step 4: Disconnect the fuel tank connections

• Use a fuel line disconnect tool to separate the fuel feed line.
• Disconnect the electrical connector going to the fuel pump module.
• Disconnect any vapor lines or vent hoses attached to the tank.
• Label every hose before removal.

Step 5: Support and lower the fuel tank

• Place the floor jack rated 3-ton minimum under the tank with a wood block if needed.
• Use a 12mm socket or 14mm socket to remove the tank strap bolts.
• Lower the tank slowly and check for any line or connector still attached.
• Remove the tank from under the truck once it is free.

Step 6: Remove the fuel pump module

• Clean the top of the tank with shop towels before opening it.
• Use a trim tool or plastic scraper to remove dirt around the pump cover area.
• Remove the lock ring or retainer carefully.
• Lift the fuel pump module straight up and out of the tank.
• Remove the old seal and strainer.

Step 7: Install the new fuel pump module

• Install the new fuel pump tank seal in the correct groove.
• Lower the new fuel pump assembly into the tank without damaging the float arm.
• Install the lock ring or retainer.
• Torque to 50 Nm (37 ft-lbs) if a serviceable retainer torque specification applies to your lock ring style.
• Make sure the seal stays seated.

Step 8: Reinstall the tank

• Raise the tank with the floor jack until the connections can be reattached.
• Reconnect the vapor lines, electrical connector, and fuel line.
• Use the 12mm socket or 14mm socket to reinstall the tank straps.
• Torque to 37 Nm (27 ft-lbs) for the strap bolts unless your service data for your trim specifies otherwise.

Step 9: Reinstall shields and lower the vehicle

• Reinstall any skid plate or shield using the 10mm socket, 12mm socket, or 14mm socket.
• Lower the truck off the jack stands.
• Reconnect the negative battery terminal with the 10mm socket.

Step 10: Prime and test the system

• Cycle the ignition key ON for a few seconds, then OFF, several times to prime the system.
• Start the engine and check for fuel leaks at the tank, line, and fittings.
• Verify normal idle and fuel pump operation.
• Stop immediately if you smell raw fuel.

✅ After Repair
