🔧 Ridgeline - Fuel Pump Module Replacement

The electric fuel pump sits inside the fuel tank and is reached through a service opening beneath the rear-seat area. Replacing it requires relieving fuel pressure, removing the rear seat and access cover, disconnecting the fuel line, and installing a complete pump module with a new seal and locknut.

Difficulty Level: Advanced | Estimated Time: 3-5 hours

Important: Your Ridgeline may qualify for Honda’s fuel-pump impeller safety recall. Check its recall status with an authorized Honda dealer before purchasing parts because eligible replacement is performed free of charge.

⚠️ Safety & Precautions

• 🔥 Work outdoors or in an extremely well-ventilated area. Gasoline vapor can ignite explosively.
• 🚭 Do not smoke or use heaters, lamps, power tools, or anything capable of producing a spark nearby.
• 🧯 Keep an automotive Class B fire extinguisher within reach.
• 🥽 Wear safety glasses and fuel-resistant nitrile gloves.
• ⚡ Relieve fuel pressure before opening the fuel system, then disconnect the negative battery cable.
• ⛽ Perform this repair with the tank below one-quarter full. A full tank increases spill and vapor hazards.
• 🧼 Clean the module area completely before opening the tank. Dirt inside the tank can damage the new pump and injectors.
• 🚫 Never test the pump by applying power outside the fuel tank.
• 🔧 Do not strike the locknut with a steel punch. Sparks near gasoline vapor can cause a fire.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve Fuel-System Pressure

• Use the owner’s manual and the fuse-box legend to identify and remove the fuel-pump fuse with needle-nose pliers. Do not substitute a similarly named fuse.
• Start the engine and let it run until it stalls. Crank it for approximately five additional seconds, then switch the ignition off.
• Reinstall the original fuse with needle-nose pliers after pressure has been relieved.
• Place clean lint-free shop towels around the future fuel-line connection because a small amount of pressurized fuel may remain.

Step 2: Disconnect the Battery

• Open the hood and use a 10mm socket and ratchet to loosen the negative battery-terminal clamp.
• Remove the negative clamp and isolate it where it cannot spring back onto the terminal.
• Wait at least three minutes before disturbing wiring around the rear seat.
• Photograph connectors before disconnecting them.

Step 3: Raise and Remove the Rear Seat Assembly

• Raise the rear-seat cushions using their normal release handles and remove any stored items.
• Use a non-marring trim removal tool to remove the bolt covers without scratching the interior.
• Use the correctly fitting 12mm or 14mm socket, extension, and ratchet to remove the rear-seat mounting bolts. Keep each bolt in its original location.
• Disconnect any seat electrical connector by releasing its lock with a small flat-blade screwdriver; never pull on the wires.
• With a helper, lift the seat assembly clear of the cabin. It is awkward and can damage trim if dragged.
• During installation, tighten the seat mounting fasteners to the specification identified for their exact size in Honda service information. Do not estimate this safety-critical seat torque.

Step 4: Expose the Fuel-Pump Service Cover

• Use a non-marring trim removal tool to release the rear-floor trim and carefully fold the carpet and insulation away from the service opening.
• Use a 10mm socket and ratchet to remove any bolted cover fasteners, if fitted.
• If the cover is bonded with sealer, use a non-marring trim removal tool to lift it gradually without bending it.
• Move the cover aside while keeping dirt away from its sealing surface.

Step 5: Clean and Identify the Connections

• Use a dry-debris shop vacuum to remove loose dirt around the unopened module. Do not use the vacuum if liquid fuel or strong concentrated vapor is present.
• Use low-pressure compressed air and safety glasses to clear the remaining dust away from the locknut.
• Use clean lint-free shop towels to wipe the module top completely clean.
• Mark the module’s installed direction with a small flat-blade screwdriver only on the surrounding metal service area, away from hoses and wiring.

Step 6: Disconnect the Wiring and Fuel Line

• Use a digital multimeter set to DC volts to confirm there is no voltage at the pump power terminals before continuing.
• Release the electrical connector lock with a small flat-blade screwdriver and unplug the connector by holding its housing.
• Place a fuel-safe drain pan and clean lint-free shop towels beneath the fuel connection.
• Remove the connector’s secondary retainer with a small flat-blade screwdriver.
• Use the Honda-compatible fuel-line quick-disconnect tool to release the fitting, then pull the line straight off without twisting the plastic outlet.
• Cap the open line with a clean lint-free shop towel positioned so no fibers enter the fitting.

Step 7: Remove the Fuel-Pump Module

• Fit the Honda-compatible fuel tank locknut wrench squarely over the locknut.
• Use the 3/8-inch drive ratchet and locknut wrench to rotate the locknut counterclockwise. Do not use a hammer or steel punch.
• Remove and discard the old locknut.
• Lift the pump module slowly while using the fuel-safe drain pan to catch fuel.
• Tilt the module only enough to guide the float arm through the opening without bending it.
• Remove and discard the old sealing gasket. Do not let it fall into the tank.

Step 8: Install the New Module

• Use clean lint-free shop towels to clean the tank’s gasket channel. Do not push dirt into the tank.
• Install the new fuel pump module sealing gasket dry and evenly in its channel. Do not apply grease, silicone, or fuel to the gasket.
• Guide the new module and float arm into the tank without forcing or bending them.
• Align the module’s index mark with the tank mark so the outlet and wiring face their original directions.
• Press the module down evenly and start the new locknut by hand. If it binds, remove it and restart it rather than forcing the threads.
• Use the Honda-compatible fuel tank locknut wrench and torque wrench to tighten the new locknut to 93 Nm (69 ft-lbs).
• Keep the gasket flat while tightening.

Step 9: Reconnect the Fuel Line and Wiring

• Inspect the quick connector for damage and install the new fuel-line quick-connector retainer.
• Push the fuel line straight onto the module outlet until it clicks.
• Pull gently on the line by hand to verify that it is locked. Do not pull on the hose itself.
• Reconnect the electrical plug until its locking tab clicks.

Step 10: Perform the First Leak Check

• Keep the service cover and carpet removed so the module remains visible.
• Reconnect the negative battery terminal with a 10mm socket and torque wrench. Tighten it to 5.4 Nm (48 in-lbs).
• Switch the ignition to ON for two seconds without starting the engine, then switch it OFF for ten seconds. Repeat this cycle three times to prime the system.
• Use a bright visual inspection and clean lint-free shop towels to check the locknut and fuel connection for wetness or fuel odor.
• If any leak appears, switch the ignition off immediately, disconnect the negative battery cable with a 10mm socket, and correct the seal or connector before proceeding.

Step 11: Reinstall the Service Cover and Interior

• After confirming there are no leaks, switch the ignition off and disconnect the negative battery cable again with a 10mm socket.
• Apply fuel pump service-cover butyl sealer continuously around the cover flange, matching the original sealing path.
• Reinstall the cover. Use a 10mm socket and ratchet for any original cover fasteners, tightening them only until the cover is seated without distortion.
• Return the insulation and carpet to their original positions and engage the trim using a non-marring trim removal tool.
• With a helper, position the rear seat without trapping wiring or seat belts.
• Reconnect the seat electrical connector and confirm its lock is fully engaged.
• Install the original seat fasteners with the appropriate 12mm or 14mm socket, then tighten them to the applicable Honda service specification for the fastener location.
• Reinstall the bolt covers with the non-marring trim removal tool.
• Reconnect the negative battery terminal with a 10mm socket and tighten it to 5.4 Nm (48 in-lbs).
