⚠️ Safety & Precautions

• 🔥 Work outdoors or in a properly ventilated shop. Gasoline vapor can ignite from a tiny spark.
• 🧯 Keep an ABC-rated fire extinguisher within reach. Do not smoke, weld, grind, or use incandescent work lights.
• 🥽 Wear safety glasses and fuel-resistant nitrile gloves.
• 🛢️ Reduce the tank below one-quarter full before starting. Gasoline weighs approximately 2.8 kg per 4 liters.
• ⚡ Relieve fuel pressure before opening a line, then disconnect the negative battery cable.
• 🚫 Never use an electric drill or steel punch near an open fuel tank.
• ⬆️ Support your F-150 only at approved frame lifting points. Never work beneath a vehicle supported only by a jack.
• 🧱 The tank must remain supported while its straps are removed. A partly filled tank can shift suddenly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve Fuel-System Pressure

• Connect the OBD-II bidirectional scan tool beneath the driver-side dashboard.
• Use the scan tool’s Ford service function to disable the fuel pump or command fuel-pressure release. A bidirectional scan tool can command vehicle modules, not merely read codes.
• Start your F-150 and allow it to idle until it stalls. Crank for approximately five seconds afterward.
• Switch the ignition off and remove the scan tool.
• Place the 10-liter fuel-safe drain pan below the connection before opening any fuel line.

Step 2: Disconnect the Battery

• Open the hood and use a 10mm socket with the 1/4-inch drive ratchet to loosen the negative battery terminal.
• Remove the negative terminal and isolate it where it cannot spring back onto the battery post.
• Wait at least one minute before disconnecting fuel-system wiring.

Step 3: Raise and Support the Truck

• Use the 3-ton floor jack at an approved rear frame lifting point to raise your F-150.
• Position the 3-ton jack stands beneath both rear frame rails, then lower the truck onto them.
• Leave the rear axle free so there is enough room to lower the tank.
• Push lightly on the truck to verify that it is stable before going underneath.

Step 4: Remove the Tank Shield If Equipped

• Support the tank shield by hand or with the transmission jack.
• Use the correctly fitting socket from the 10mm-18mm socket set, 3/8-inch drive ratchet, and 150mm extension to remove the shield fasteners.
• Lower the shield carefully and keep its fasteners organized by position.

Step 5: Disconnect the Filler and Vent Connections

• Use the plastic trim-clip removal tool to release the filler-pipe and vapor-line retainers without breaking them.
• Use the correct socket from the 7mm-13mm socket set and 1/4-inch drive ratchet to loosen any hose clamp fitted at the tank connection.
• Use the 6mm flat-blade screwdriver only to release a locking tab. Do not pry against or puncture a plastic fitting.
• Twist the filler hose gently and pull it from the tank neck. Disconnect the smaller vent connection in the same area.
• Place absorbent pads below the connections to catch residual fuel.

Step 6: Support the Fuel Tank

• Center the 450kg transmission jack beneath the tank and secure the tank with the jack’s strap.
• Raise the transmission jack only until it contacts and supports the tank. Do not lift the truck from its stands.
• A helper makes tank control much safer.

Step 7: Remove the Tank Straps

• Use the correctly fitting socket from the 10mm-18mm socket set, 3/8-inch drive ratchet, and 150mm extension to remove the tank-strap bolts.
• Swing the straps away while keeping the tank fully supported by the transmission jack.
• Inspect the straps and insulating pads. Replace damaged parts before reinstalling the tank.

Step 8: Lower the Tank Partway

• Use the transmission jack to lower the tank only far enough to reach its upper connections.
• Watch every hose and wire while lowering. Stop immediately if anything becomes tight.
• Use the LED work light to identify the pump-module connector, fuel line, and vapor lines.

Step 9: Disconnect the Pump Wiring and Lines

• Use the plastic trim-clip removal tool to release the electrical connector’s secondary lock, then press its latch and unplug it.
• Use the appropriate 5/16-inch or 3/8-inch fuel-line disconnect tool to release any spring-lock fuel fitting. Push the line inward first, insert the tool, and then pull the line free.
• For tab-style connectors, use the 6mm flat-blade screwdriver to unlock only the colored safety clip, then press the connector tabs by hand.
• Catch residual gasoline in the 10-liter fuel-safe drain pan and cover the open connections with clean absorbent material.
• Use the plastic trim-clip removal tool to release the remaining vapor-line retainers.

Step 10: Remove the Tank

• Verify visually with the LED work light that no wiring, fuel lines, vapor lines, or filler hoses remain connected.
• Use the transmission jack to lower the tank slowly.
• Roll the tank from beneath your F-150 and move it to a clean, ventilated work area away from ignition sources.

Step 11: Clean the Pump Area

• Use the 25mm soft nylon brush to loosen dirt from the top of the tank.
• Use the regulated compressed-air blow gun to direct debris away from the module opening. Wear ANSI-rated safety glasses.
• Clean until no loose dirt remains around the retaining ring.

Step 12: Remove the Old Pump Module

• Mark the module’s installed orientation so the replacement faces the same direction.
• Fit the specialty fuel pump lock-ring wrench over the retaining ring.
• Use the 16-ounce non-sparking dead-blow hammer on the lock-ring wrench to rotate the ring counterclockwise. Do not use a steel punch.
• Remove the retaining ring, then lift the module slowly while guiding the fuel-level float through the opening.
• Allow fuel inside the module reservoir to drain into the tank before removing it completely.
• Remove and discard the old O-ring seal.

Step 13: Install the New Pump Module

• Clean the sealing groove with a fresh absorbent pad. Do not use silicone, grease, or gasket sealer.
• Install the new dry O-ring seal squarely in the tank groove.
• Lower the new module into the tank while guiding the float arm carefully. Do not bend the arm.
• Align the module with the orientation mark and locating tabs.
• Install a serviceable retaining ring. Use the fuel pump lock-ring wrench and 3/8-inch drive torque wrench to tighten the ring to Torque to 80 Nm (59 ft-lbs).
• Confirm that the ring is fully engaged beneath every tank retaining tab and that the O-ring has not pushed out.

Step 14: Reinstall and Connect the Tank

• Place the tank on the transmission jack, secure its strap, and raise it partway.
• Push each fuel-line connector onto its matching fitting by hand until it clicks. Pull back gently to verify that it is locked.
• Reconnect each vapor line by hand and reinstall its locking clip with the plastic trim-clip removal tool.
• Reconnect the electrical plug by hand and engage its secondary lock.
• Raise the tank into position while checking that no line is pinched above it.

Step 15: Install the Tank Straps and Filler Connections

• Position both straps and start every strap bolt by hand to prevent crossed threads.
• Use the correct socket from the 10mm-18mm socket set and the 3/8-inch drive torque wrench to tighten the tank-strap bolts to Torque to 47 Nm (35 ft-lbs).
• Push the filler and vent connections fully into place by hand.
• Use the correct socket from the 7mm-13mm socket set and 1/4-inch drive ratchet to secure the original hose clamp. Tighten it only until the hose cannot rotate; do not crush the plastic tank neck.
• Use the plastic trim-clip removal tool to reinstall all line and harness retainers.

Step 16: Install the Shield and Lower the Truck

• Position the shield and start all fasteners by hand.
• Use the matching socket from the 10mm-18mm socket set and 3/8-inch drive torque wrench to tighten the shield fasteners to Torque to 28 Nm (21 ft-lbs).
• Use the 3-ton floor jack to lift your F-150 slightly, remove both 3-ton jack stands, and lower the truck to the ground.

Step 17: Reconnect and Prime the Fuel System

• Use the 10mm socket and 1/4-inch drive ratchet to reconnect the negative battery terminal. Tighten it securely without crushing or twisting the terminal.
• Without pressing the brake pedal, switch the ignition on for five seconds and then off for ten seconds. Repeat this cycle four times.
• Start the engine and let it idle. Extended cranking on the first start can be normal while the module fills.
• Use the LED work light to inspect the tank, filler connection, and fuel-line connections for leaks. Shut the engine off immediately if you see or smell leaking fuel.

✅ After Repair

• 🔍 Let the engine idle for five minutes while checking for leaks, unusual pump noise, or a fuel odor.
• 📟 Connect the OBD-II bidirectional scan tool and clear fuel-pressure or fuel-level codes caused during service.
• 📊 Use the scan tool to confirm that commanded and actual fuel pressure are stable. A new pump will not correct a failed driver module, damaged wiring, or restricted fuel line.
• ⛽ Add approximately 15 liters of fuel and verify that the dashboard fuel gauge responds normally.
• 🚗 Take a short low-speed test drive, then park and perform another leak inspection.
• 🛑 Do not drive your F-150 if gasoline odor persists or the tank shows any wetness.
