🔧 Fuel Pump - Replacement

The fuel pump on your Explorer is inside the fuel tank, so the tank must be lowered to replace the pump module. This is a messy, safety-sensitive job because you’ll be working with fuel vapors, fuel lines, and a heavy tank.

Difficulty Level: Advanced | Estimated Time: 4-7 hours

⚠️ Safety & Precautions

• Work only in a well-ventilated area away from sparks, flames, and heaters.
• Disconnect the negative battery cable before starting.
• Relieve fuel system pressure before opening any fuel lines.
• Fuel may still spill when the lines are disconnected; wear eye protection and gloves.
• The fuel tank is heavy and awkward. Use a transmission jack or a sturdy floor jack with a wide support surface.
• Keep the tank as close to empty as possible before removal.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Run the tank low before starting. Less fuel makes the tank easier and safer to lower.
• Disconnect the negative battery cable using an 8mm socket.
• Relieve fuel pressure at the service point if equipped, or follow the fuel pump fuse/relay pressure bleed procedure.
• Label every hose before disconnecting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel system pressure

• Use the correct fuel pressure bleed procedure for the fuel system before disconnecting lines.
• If using a scan tool or fuse method, make sure the engine stalls and cranks briefly with pressure relieved.
• Open the fuel filler cap carefully after pressure is relieved.

Step 2: Disconnect the battery

• Use an 8mm socket to disconnect the negative battery cable.
• Move the cable aside so it cannot touch the terminal.

Step 3: Raise and support the vehicle

• Use a floor jack and jack stands to raise and support the Explorer safely.
• Make sure the vehicle is stable before working underneath it.

Step 4: Remove underbody shields and supporting components

• Use the correct socket set and ratchet to remove any shields blocking the fuel tank.
• On AWD models, inspect for exhaust and driveshaft clearance. Remove any components that prevent safe tank removal.

Step 5: Support the fuel tank

• Place a transmission jack or wide-support jack under the fuel tank.
• Raise it just enough to hold the tank securely.
• Never let the tank hang by the hoses.

Step 6: Disconnect filler and vent hoses

• Use a flat trim tool if clamps or retainers need gentle release.
• Disconnect the fuel filler neck, vent hoses, and evaporative lines.
• Mark each connection so it goes back in the correct place.

Step 7: Disconnect electrical connectors and fuel lines

• Use a fuel line disconnect tool set to release the fuel supply and return lines.
• Disconnect the fuel pump electrical connector.
• Have a fuel-safe drain pan and shop rags ready for spill control.

Step 8: Lower the fuel tank

• Use the socket set and ratchet to remove the tank strap bolts.
• Lower the tank slowly with the jack.
• Check one more time that no hose or wire is still attached.

Step 9: Remove the fuel pump module

• Clean the top of the tank with shop air or a brush before opening it.
• Use a brass punch and non-sparking hammer to remove the lock ring if the design uses one.
• Lift the old fuel pump module out carefully.
• Remove the old seal ring from the tank.

Step 10: Install the new fuel pump module

• Install the new fuel tank seal ring on the tank opening.
• Lower the new fuel pump module into place in the same orientation as the old one.
• Install and lock the retaining ring fully.
• Torque the retaining ring to factory specification if a torque spec is provided by the service procedure.

Step 11: Reinstall the fuel tank

• Raise the tank slowly with the jack.
• Reconnect the fuel lines with the fuel line disconnect tool set.
• Reconnect the electrical connector, filler neck, vent hoses, and EVAP lines.
• Reinstall the tank straps and tighten the strap bolts.
• Torque the tank strap bolts to factory specification.

Step 12: Reinstall shields and lower the vehicle

• Reinstall all shields and removed parts using the correct socket set.
• Lower the Explorer off the jack stands.
• Reconnect the negative battery cable with an 8mm socket.

✅ After Repair

• Cycle the key to ON several times before starting to prime the fuel system.
• Check carefully for fuel leaks at the tank, lines, and filler neck.
• Start the engine and let it idle while watching for leaks or fuel smell.
• Clear any fuel system codes with a scan tool if needed.
• If the fuel gauge reads incorrectly, verify connector seating and scan for related faults.
