2008 Honda Pilot Fuel Pump: The Complete Replacement and Buying Guide

If you own a 2008 Honda Pilot and suspect the fuel pump is failing, the single most important thing you need to know is this: the original equipment fuel pump for your vehicle is part number 17045-S9V-A00, which replaces the earlier 17045-S3V-A01, and it fits every 2008 Pilot trim level including EX, EX-L, Special Edition, and Value Package models. A failing fuel pump will not fix itself, and delaying replacement can leave you stranded or cause damage to other fuel system components. This guide walks you through how to recognize a failing pump, what your replacement options are, how to choose the right part, and what the replacement process involves so you can make an informed decision with confidence.

How to Tell Your 2008 Honda Pilot Fuel Pump Is Going Bad

The fuel pump in your 2008 Honda Pilot is an electric in-tank unit that pressurizes the fuel rail so the engine receives a steady supply of gasoline. When it starts to wear out, it rarely fails without warning. Most owners notice one or more of the following symptoms before the pump gives out completely:

  1. Hard starting – The engine cranks longer than usual before firing up. This happens because the pump cannot build enough fuel pressure quickly.
  2. Sputtering at highway speed – If the car loses power momentarily or surges while cruising, the pump may be struggling to deliver a consistent flow.
  3. Whining noise from the fuel tank – A healthy pump runs quietly. A loud, high-pitched whine from the rear of the vehicle usually means the pump motor is straining.
  4. Sudden stalling – The engine dies while driving, then restarts after sitting for a few minutes. This is a classic sign of an overheating or failing pump.
  5. Poor fuel economy – A pump that is not maintaining proper pressure forces the engine to run rich, which burns more gas.

These symptoms can also be caused by a clogged fuel filter, a faulty fuel pressure regulator, or even a bad fuel pump relay, so a proper diagnosis is important before spending money on a new pump.

What Fuel Pump Does the 2008 Honda Pilot Use?

The 2008 Honda Pilot uses a fuel pump module assembly (also called a fuel pump and sender assembly) that sits inside the fuel tank. This module includes not just the electric pump itself but also the fuel sending unit that measures how much fuel is in the tank and sends that reading to the dashboard gauge.

The OEM (original equipment manufacturer) part number is 17045-S9V-A00 for the 2008 model year. This same part also fits the 2005, 2006, and 2007 Pilot, making it a widely available, proven component. The earlier part number 17045-S3V-A01 was superseded by this newer version, so if you see the older number, it has been replaced by 17045-S9V-A00.

The complete list of 2008 Honda Pilot trims that use this fuel pump assembly includes:

  • 5 Door EX (2WD and 4WD)
  • 5 Door EX-L (2WD and 4WD)
  • 5 Door EX-SE (2WD and 4WD)
  • 5 Door LX-VP (2WD and 4WD)

All of these trims use the same 3.5L V6 engine, so the fuel pump is identical across the lineup.

OEM vs. Aftermarket Fuel Pump: Which Should You Choose?

When it comes time to replace the fuel pump in your 2008 Pilot, you have two main categories to consider: genuine OEM parts and aftermarket replacements. Each has its own advantages.

Genuine Honda OEM Fuel Pump (17045-S9V-A00)

The genuine Honda part is made to the exact specifications of the original pump that came in your vehicle. It is a direct replacement unit, meaning it bolts in with no modifications needed. The OEM pump is manufactured by Honda with factory-grade materials and is backed by Honda's factory warranty.

  1. Pros – Perfect factory fit, proven reliability, maintains the vehicle's original performance standards.
  2. Cons – Higher price point. The OEM assembly typically retails between $435 and $475 at authorized dealers, with list prices sometimes exceeding $628.
  3. Best for – Owners who want absolute peace of mind and plan to keep their Pilot for many more years.

Aftermarket Fuel Pumps

Aftermarket pumps come from a variety of brands, from well-known names like Bosch, Delphi, and Carter to specialized aftermarket manufacturers. These parts are designed to meet or exceed the original equipment specifications and are generally more affordable.

  1. Pros – Lower cost than genuine OEM parts, broad availability, often include additional components like new seals and gaskets.
  2. Cons – Quality varies significantly by brand. Some budget pumps may not match the durability of the original equipment.
  3. Best for – Budget-conscious owners who want a reliable replacement without paying the OEM premium.

When choosing an aftermarket pump, pay attention to whether the part includes the fuel sending unit (the float assembly that measures fuel level). Some cheaper pumps are sold without the sending unit, which means you would need to transfer the old one over – doable, but an extra step.

Aftermarket Fuel Pump Options for the 2008 Honda Pilot

Several reputable aftermarket brands make fuel pumps that directly replace the OEM unit in the 2008 Pilot. Here is a breakdown of common options you will find online and in auto parts stores:

  1. DriveMotive Fuel Pump (Part # 18375-03603676) – A direct-fit replacement sold by PartsGeek. It includes the fuel sending unit and uses a 4-prong blade connector. Flow rate is rated at 26 gallons per hour, which matches the demands of the 3.5L V6. Priced around $66, this is one of the more budget-friendly options.

  2. Carter Fuel Pump Module Assembly (Part # P76306M / 18375-09423640) – A complete module assembly made by Carter, a well-established fuel systems brand. This unit includes the sending unit, a new tank seal, and a strainer. It is made with all-new materials and comes with a white trapezoid electrical connector. Priced around $234, it sits in the mid-range of aftermarket pricing.

  3. A-Premium Fuel Pump with Sending Unit (APFP0184) – A direct replacement that fits 4-pin connectors, includes the sending unit and float, and carries a 3-year warranty. Priced around $101. A-Premium also offers several other variants for the 2008 Pilot at different price points, ranging from $44 to $101 depending on the exact configuration.

  4. Bosch Electric Fuel Pump (Part # 69544) – Bosch is a globally recognized brand known for quality fuel delivery components. This in-tank pump is sold at around $106 and is a straightforward replacement for the pump itself, though you may need to reuse the original module housing.

  5. Delphi Fuel Pump Module Assembly (Part # FG0930) – Delphi is another premium brand. Their module assembly for the 2008 Pilot is priced around $324 and includes the sending unit. Delphi also lists interchange numbers matching the Honda OEM part, confirming direct fitment.

Each of these aftermarket options is designed to work with the 2008 Honda Pilot's factory fuel system, but the exact fitment can vary slightly depending on your vehicle's trim and whether your truck has 2WD or 4WD.

How to Replace the Fuel Pump in a 2008 Honda Pilot

Replacing the fuel pump in a 2008 Pilot is a job that many home mechanics can tackle with basic hand tools and a few hours of time. The pump is located inside the fuel tank, which means you need to drop the tank or, on some models, access it through a service panel under the rear seat. On the 2008 Pilot, the access point is under the rear seat area, but in practice most replacements require lowering the tank slightly to disconnect lines and the electrical connector.

Here is the general process:

  1. Depressurize the fuel system – Remove the fuel pump relay or fuse and crank the engine until it stalls. This releases pressure in the lines.
  2. Disconnect the battery – Always disconnect the negative battery cable before working on any fuel system component.
  3. Access the fuel pump – On the 2008 Pilot, this typically involves removing the rear seat bottom and opening the access cover, then disconnecting the fuel lines and electrical harness. If there is no access cover, you will need to lower the fuel tank.
  4. Remove the old pump module – Use a special spanner wrench or a hammer and brass punch to remove the locking ring that holds the module in place. Lift the module out of the tank, being careful not to damage the float arm.
  5. Install the new pump – Transfer any components that do not come with your new pump (if you bought one without a sending unit). Install the new module, making sure the float arm is positioned correctly, and tighten the locking ring.
  6. Reconnect everything – Reattach fuel lines and electrical connectors, reinstall the access cover and seat, and reconnect the battery.
  7. Test the system – Turn the ignition to the "ON" position (without starting the engine) to prime the fuel pump. Listen for a brief whirring sound, check for leaks, then start the engine.

One important note: always replace the fuel pump with the vehicle on a flat surface and never smoke or use an open flame near the work area. Fuel vapors are highly flammable.

How Much Does a 2008 Honda Pilot Fuel Pump Replacement Cost?

The cost of replacing the fuel pump on a 2008 Pilot depends heavily on whether you do the work yourself or hire a mechanic, and whether you choose an OEM or aftermarket part.

  1. Parts only – Aftermarket pump modules range from roughly $44 for basic A-Premium units to around $234 for a complete Carter assembly. Genuine Honda OEM pumps run between $435 and $475.
  2. DIY labor – If you do the job yourself, your total cost is just the price of the part. Expect to spend 2 to 4 hours on the job.
  3. Professional installation – If you pay a shop to do the work, labor typically adds another $200 to $400 on top of the part price. This means a total cost ranging from roughly $250 (aftermarket part, inexpensive shop) to over $800 (OEM part, dealership labor).

The OEM pump's list price is $628.53, though many dealers sell it for less. Whether the extra cost of the genuine Honda part is worth it depends on how long you plan to keep the vehicle and how much you value factory-original components.

Tips for Getting the Most Life Out of Your New Fuel Pump

Once you install a new fuel pump, you want it to last as long as possible. Fuel pumps typically last 100,000 miles or more, but a few habits can extend that life:

  1. Keep the tank at least a quarter full – Running on an empty tank causes the pump to run hotter and can pick up sediment from the bottom of the tank.
  2. Replace the fuel filter regularly – A clogged filter forces the pump to work harder and shortens its lifespan.
  3. Use quality fuel – Cheap, low-quality gasoline can contain water and contaminants that accelerate pump wear.
  4. Fix fuel leaks promptly – A leak in the fuel system can cause the pump to run continuously or intermittently, stressing the motor.

Know Which Part Fits Your 2008 Pilot Before You Order

Before you buy any fuel pump, confirm your vehicle's exact trim and drivetrain. While the 2008 Pilot uses the same engine across all trims, some aftermarket listings show slightly different fitment data for 2WD versus 4WD models. When in doubt, use the OEM part number 17045-S9V-A00 as your reference point – any aftermarket part that lists this interchange number is confirmed to fit your truck.

Also pay attention to the electrical connector type. The 2008 Pilot uses a 4-pin blade connector, but some aftermarket pumps are sold with a different connector style. If the new pump does not match your vehicle's harness, you will need an adapter, which adds complexity and potential failure points.

Final Thoughts

The bottom line is simple: when your 2008 Honda Pilot needs a fuel pump, the best choice is a direct replacement that matches the OEM part number 17045-S9V-A00, whether you buy the genuine Honda part or a quality aftermarket equivalent. A failing fuel pump will only get worse over time, and the symptoms – hard starts, sputtering, whining, stalling – will eventually leave you stranded. The good news is that the replacement process is well-documented, parts are widely available, and you have options that fit every budget from under $50 to over $400.
