2006 Honda Pilot Fuel Pump Location: A Complete Guide to Finding and Replacing It

If you drive a 2006 Honda Pilot and suspect a fuel delivery problem, the fuel pump sits inside the fuel tank, under the rear passenger seat, and is accessible through a service panel after removing the seat and carpet. This in-tank placement is standard for modern vehicles because it keeps the pump cool and reduces vapor lock, but it also means replacement requires methodical work. The good news? On 2003-2008 Pilot models, you do not need to drop the fuel tank to reach the pump, which saves significant time and labor. Below, we walk you through the exact location, the warning signs of failure, and a step-by-step replacement process, plus our recommendation for a high-quality replacement part.

Where Exactly Is the Fuel Pump in a 2006 Honda Pilot?

The fuel pump on your 2006 Pilot is not bolted to the frame or mounted externally like older mechanical pumps. Instead, it is part of a fuel pump module assembly that sits inside the fuel tank itself. To access it, you start inside the cabin: the second-row seat on the passenger side must be removed, then the carpet peeled back to reveal a metal access cover. That cover exposes the pump's wiring harness and fuel lines, giving you a direct path to the pump assembly without touching the tank's exterior.

This design is common across the 2003-2008 Honda Pilot generations, so the procedure is the same whether your Pilot is a 2005, 2006, or 2007 model year. The OEM part number for the complete fuel pump module on the 3.5L V6 is 17045-S9V-A00, which supersedes the earlier 17045-S3V-A01. This assembly includes not just the electric pump, but also the fuel level sending unit, strainer, and pressure regulator, all in one unit.

How Can You Tell the Fuel Pump Is Going Bad?

Several symptoms point to a failing fuel pump, and catching them early prevents a roadside breakdown. Look for these common warning signs:

1. Sputtering at speed. If the engine hesitates or loses power when you accelerate, especially on highways, the pump cannot keep up with fuel demand.
2. Hard starting. A weak pump fails to prime the system, so the engine cranks longer than usual before firing.
3. Whining from the tank. When you turn the key to the "On" position (without starting), the pump should make a quiet, consistent hum. A loud whine or buzzing means the pump is wearing out.
4. Loss of power under load. Climbing hills or towing makes a failing pump obvious, as the engine feels sluggish.
5. Engine surging. Inconsistent fuel pressure causes sudden, unintended acceleration surges at steady speeds.
6. Poor fuel economy. A pump running inefficiently can make the engine run rich or lean, hurting mileage.

If you notice any of these, test the basics first. Check the 15A fuel pump fuse in the interior fuse box on the driver's side, listen for the priming hum, and if possible, test fuel pressure at the rail, which should sit between 45 and 55 psi for the 2006 Pilot. Low pressure could indicate a failing pump, a clogged filter, or a faulty pressure regulator, so do not skip diagnosis.

Step-by-Step Guide to Accessing and Replacing the Pump

Replacing the fuel pump on a 2006 Honda Pilot is a DIY-friendly job if you are comfortable with basic car maintenance, and it typically takes 3 to 5 hours. Here is how to do it safely and correctly.

1. Relieve Fuel Pressure and Disconnect the Battery

Start by opening the fuel filler door and loosening the gas cap to vent the tank. Then, in the under-hood fuse box, remove the fuel pump fuse or relay, start the engine, and let it run until it stalls. This releases the pressure from the system. Crank the engine for another 2-3 seconds to bleed any remaining pressure, then turn the ignition off and reinstall the fuse or relay. Next, disconnect the negative battery terminal with a 10mm socket and isolate it so it cannot touch the battery post. This prevents any accidental electrical shorts or sparks.

2. Access the Pump Through the Rear Seat

Move the second-row passenger side seat as needed and remove any trim fasteners with a trim clip remover. Carefully peel back the carpet to expose the metal access cover, then remove the screws or bolts using a Phillips screwdriver or 10mm socket. You will now see the top of the fuel pump module and its wiring harness.

3. Disconnect Electrical Connector and Fuel Lines

Clean the area around the pump flange thoroughly with shop towels to prevent dirt from falling into the tank. Unplug the pump's electrical connector by pressing the release tab and pulling it straight off. Place a drain pan under the fuel lines to catch residual fuel, then use a fuel line disconnect tool set to release the quick-connect fittings. Press the tool into the fitting until you feel release, then pull the line off carefully to avoid damaging the O-rings.

4. Remove the Old Pump Module

Use a fuel pump lock ring wrench or a brass punch and dead-blow hammer to loosen the locking ring that holds the module in place. Turn the ring counterclockwise until loose, then remove it by hand. Carefully lift the pump module out of the tank, tilting it as needed to clear the opening, and note its orientation for reinstallation. Place the module in a clean drain pan to catch any remaining fuel.

5. Install the New Pump Module

Place a new fuel pump module seal or O-ring into the groove on the tank opening. Lower the new pump module into the tank, ensuring the fuel level sender is positioned so the float does not hit the tank walls. Press down until seated, then install the locking ring and tighten it clockwise using the lock ring wrench or brass punch. Torque the ring to manufacturer specifications, typically 30-40 ft-lbs, but check your service manual.

6. Reconnect Everything and Test

Push the fuel lines onto the fittings until they click into place, then gently pull to confirm they are locked. Apply a small amount of dielectric grease to the electrical connector terminals, plug it in until it snaps. Reinstall the access cover and carpet, reconnect the negative battery terminal, then turn the ignition to "On" (do not start) and listen for the pump to prime with a 2-3 second hum. Turn the ignition off and on again several times to build pressure, check all connections for leaks, then start the engine and verify smooth operation.

Should You Replace Just the Pump or the Whole Module?

Many mechanics recommend replacing the entire fuel pump module assembly rather than just the pump motor inside it. A complete module includes the fuel level sending unit, strainer, and pressure regulator, and these components wear at similar rates. Replacing the whole assembly gives you long-term reliability and avoids the need to transfer parts, which reduces the chance of future failures. The genuine Honda module for the 2006 Pilot, part number 17045-S9V-A00, typically costs between $435 and $630, depending on where you buy it.

How Much Does Professional Replacement Cost?

If you prefer to have a shop do the work, budget for both parts and labor. The fuel pump assembly itself ranges from about $120 to $700, depending on whether you choose OEM, aftermarket, or remanufactured parts. Total installed costs commonly range from $500 to $1,200. Dealer service centers tend to charge more, often $1,151 to $1,271, using manufacturer-recommended parts, while independent shops may charge between $1,104 and $1,219. The labor portion typically runs $200 to $600, with the job taking 3 to 5 hours. Always ask for an itemized quote and confirm what parts are included.
