📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Try to run the fuel level low (under 1/4 tank). A full tank is heavy and unsafe to handle.
• Relieve fuel pressure before disconnecting any fuel lines.
• Disconnect the negative battery cable using a 10mm socket.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the fuel tank setup (quick check)

• Look under the van to confirm you have one rear tank (most E-150) and identify the tank straps and filler neck.
• If you see a second tank or a tank selector setup, stop here and tell me (steps and parts change).

Step 2: Relieve fuel system pressure

• Remove the fuel pump relay from the under-hood power distribution box using your fingers or pliers if needed.
• Start the engine and let it run until it stalls. Crank for 3 seconds more.
• Turn key OFF and reinstall the relay.
• This minimizes fuel spray when lines open.

Step 3: Raise and support the van

• Use a floor jack (rated 3-ton minimum) to lift the rear.
• Set the rear frame on jack stands (rated 3-ton minimum).
• Keep the floor jack available to support the fuel tank.

Step 4: Reduce fuel weight (if needed)

• If the tank is more than 1/4 full, siphon fuel out using a hand siphon pump (specialty) into approved fuel containers.
• Place a drain pan (at least 3-gallon) under the work area.

Step 5: Support the fuel tank

• Position the floor jack (rated 3-ton minimum) under the center of the tank.
• Put a flat piece of wood (if available) between jack and tank to spread load.

Step 6: Disconnect the filler neck and vent hoses

• Loosen hose clamps using a flat-blade screwdriver.
• Work the hoses off the tank nipples by hand or with pliers carefully.
• Twist hoses gently to break them loose.

Step 7: Disconnect electrical connectors

• Unplug the fuel pump module electrical connector(s) at the tank using your hands.
• If the connector is stubborn, use a flat-blade screwdriver lightly to release the tab.

Step 8: Disconnect fuel supply/EVAP lines at the tank

• Clean dirt off the connections using shop rags so debris doesn’t fall into the lines.
• Use the fuel line disconnect tool set (spring-lock) 3/8" and 1/2" (specialty) to separate the quick-connect fittings.
• Have the drain pan (at least 3-gallon) ready for fuel drips.
• Spring-lock tools slide into the fitting to release it.

Step 9: Remove the tank straps

• Remove the tank strap fasteners using a 13mm socket or 15mm socket (varies by hardware) with a 3/8" drive ratchet and extensions.
• Lower the straps and keep the tank supported by the floor jack (rated 3-ton minimum).
• Torque to 40 Nm (30 ft-lbs) when reinstalling strap fasteners.

Step 10: Lower the fuel tank

• Slowly lower the tank using the floor jack (rated 3-ton minimum).
• Pause if anything is still attached; disconnect remaining hoses/wires by hand.
• Lower it enough to access the top of the pump module.

Step 11: Remove the fuel pump module lock ring

• Clean the top of the tank around the module using shop rags.
• Use a brass punch and hammer to tap the lock ring counterclockwise until it releases.
• Brass reduces spark risk vs steel.

Step 12: Remove the module and replace the seal

• Lift the module out carefully by hand; angle it to clear the float arm.
• Remove the old tank seal and install the new fuel pump module tank seal (O-ring) by hand.
• Transfer any required rubber isolators or components from the old module to the new one (if applicable) using a flat-blade screwdriver as needed.

Step 13: Install the new fuel pump module

• Insert the new module straight down, aligning the tabs/index marks by hand.
• Reinstall the lock ring and tap it clockwise using the brass punch and hammer until fully seated.

Step 14: Reinstall the fuel tank

• Raise the tank into position using the floor jack (rated 3-ton minimum).
• Reconnect fuel/EVAP lines using the quick-connects by hand until they click.
• Reconnect electrical connectors by hand.
• Reconnect filler and vent hoses, then tighten clamps using a flat-blade screwdriver.
• Reinstall tank straps and tighten fasteners using the correct 13mm socket or 15mm socket.
• Torque to 40 Nm (30 ft-lbs).

Step 15: Replace the fuel filter

• Locate the frame-mounted fuel filter.
• Use the fuel line disconnect tool set (spring-lock) 3/8" and 1/2" (specialty) to disconnect lines.
• Install the new fuel filter in the correct flow direction (arrow toward engine).

Step 16: Lower the van

• Raise slightly with the floor jack (rated 3-ton minimum), remove the jack stands (rated 3-ton minimum), then lower to the ground.

✅ After Repair

• Key ON (not start) for 5 seconds, key OFF for 5 seconds; repeat 3 times to prime the system.
• Start the engine and inspect for leaks at the tank, filter, and quick-connect fittings.
• Test drive 5–10 minutes, then recheck for any fuel smell or seepage.
