2010 Acura TL Fuel Pump: Location, Symptoms, Replacement Guide, and Costs

The bottom line up front: The 2010 Acura TL fuel pump is an electric pump located inside the fuel tank beneath the rear seat area, and when it fails, you will likely notice hard starting, engine stalling, or a whining noise from the tank. Replacing it costs anywhere from $250 for a quality aftermarket part to over $1,300 with labor at a professional shop, depending on your choice of OEM, aftermarket, or used components and whether you tackle the job yourself.

The 2010 Acura TL fuel pump is not located in the engine bay, which surprises many owners. Instead, it sits inside the fuel tank, a common design in modern vehicles that improves safety and keeps the pump cool by submerging it in fuel . This placement protects the pump from external damage and helps maintain consistent fuel temperature for optimal engine performance. Accessing it requires removing the rear seat cushion and the fuel tank access panel, then lowering the fuel tank slightly or removing it entirely, depending on the specific repair . This design aligns with industry trends aimed at reducing fire hazards and improving fuel system reliability.

Why the 2010 Acura TL Fuel Pump Fails

Fuel pumps in the 2010 Acura TL do not have a specific replacement interval, but they become more common as mileage increases . Repeatedly running the fuel tank low or driving with clogged fuel filters puts extra strain on the pump and shortens its lifespan . The pump must deliver the right amount of fuel at high enough pressure to keep the engine running smoothly in all conditions . Over time, wear on the electric motor, contaminated fuel, or debris in the tank can cause the pump to lose pressure or fail completely.

For the 3.5L V6 front-wheel-drive models, the main fuel pump assembly is part number 17045-TK4-A00, which lists at $620.60 MSRP and sells for around $434.54 from OEM parts suppliers . For the 3.7L V6 SH-AWD models, the main pump on the left side uses part number 17045-TK5-A10 or the updated 17045-TK5-A11, which retails around $729.10 MSRP and sells for approximately $510.52 . These OEM pumps come with Acura's factory warranty and are guaranteed to fit perfectly .

Symptoms of a Failing Fuel Pump in a 2010 Acura TL

A failing fuel pump will not create enough pressure in the fuel system, potentially resulting in a loss of engine power or a no-start condition . You may also experience a lean running condition that can set a diagnostic trouble code and turn on the Check Engine Light . Here are the most common warning signs to watch for:

  1. Engine stalling or sputtering – The engine may cut out while driving, especially at highway speeds, because the pump cannot maintain consistent fuel delivery .
  2. Difficulty starting the car – If the pump is weak, the engine may crank but take longer to fire up, or it may not start at all .
  3. Whining noise from the fuel tank – A loud, continuous whine coming from the rear of the car often indicates the pump motor is wearing out .
  4. Loss of power during acceleration – The engine may hesitate or feel sluggish when you press the gas pedal because the pump cannot supply enough fuel under load .
  5. Check Engine Light illumination – A lean running condition caused by low fuel pressure can trigger diagnostic trouble codes and turn on the warning light .

If any of these symptoms appear, get the car inspected right away. Driving with a failing fuel pump is a bad idea. In some cases, the car will not even start or run, preventing you from driving at all . If the car is running but has a lack of power or keeps stalling because of a suspected fuel pump problem, drive it to a safe spot and then have it towed to a shop for repairs .

How to Access the Fuel Pump on a 2010 Acura TL

The fuel tank on the 2010 Acura TL is positioned beneath the rear seat area . To access the pump, you need to remove the rear seat cushion and the fuel pump access panel. In some cases, you may also need to lower the fuel tank slightly or remove it entirely, depending on the repair required . The replacement is rated as moderate difficulty and requires specialized tools and fuel system knowledge . For a professional mechanic, expect about 2-3 hours of labor, while a DIY owner should budget 4-6 hours .

Before starting any work on the fuel system, always relieve the fuel system pressure to minimize the risk of fuel spray or fire. Locate the Schrader valve on the fuel rail and depressurize the system . Disconnect the negative battery terminal to prevent accidental electrical shorts . Work in a well-ventilated area and avoid open flames or sparks . Use a fuel line disconnect tool to avoid damaging the lines and have a drain pan ready to catch residual fuel . Investing in a fuel pump module removal tool can simplify the process and ensure the tank is safely lowered without causing damage to surrounding components .

OEM vs. Aftermarket vs. Used Fuel Pump Options

Choosing the right replacement pump for your 2010 Acura TL matters. Here is a breakdown of the three main options:

  1. Genuine OEM pumps – Acura factory parts are engineered for a perfect fit and maximum durability. The 2010 Acura TL fuel pump module set for the 3.5L engine (17045-TK4-A00) costs about $434.54, while the 3.7L SH-AWD version (17045-TK5-A11) runs around $510.52 . These come with Acura's factory warranty and guarantee your TL returns to factory condition .

  2. Aftermarket pumps – Brands like Delphi and TRQ offer direct replacement assemblies at competitive prices. Delphi's W0133-1838063 fuel pump assembly fits 2009-2014 TL 3.5L models and costs about $228.97, significantly less than the $620.60 OEM list price . TRQ's FPA70911 fuel pump module assembly for the 3.5L V6 includes the sending unit, lock ring, and strainer, typically priced well below OEM equivalents . Delphi builds all fuel pumps to OE standards with lower failure rates due to innovative design and durability .

  3. Used OEM pumps – Salvage yards offer significant savings. A used fuel pump assembly from a 2010-2014 TL 3.5L FWD typically costs $46.54 to $250 depending on mileage and condition . Used OEM parts are the same parts your vehicle came with from the factory, so they fit and work just like the original . Most reputable sellers provide a 6-month warranty . However, quality varies, so inspect carefully before purchasing.

Estimated Costs for a 2010 Acura TL Fuel Pump Replacement

The average cost for an Acura TL fuel pump replacement is between $1,364 and $1,409 at a professional shop . Labor costs are estimated between $97 and $142, while parts are typically priced around $1,267 . This range does not include taxes and fees and does not factor in your unique location . If you choose an OEM pump from an Acura dealer, expect to pay premium prices. Aftermarket options from brands like Delphi and TRQ can cut the parts cost dramatically, bringing the total down to $400-$600 if you use an independent mechanic or DIY .

For DIY owners, the job is doable but time-consuming. You will need a jack, jack stands, fuel line disconnect tools, and a fuel pump module removal tool . The time and risk involved make professional installation the smarter choice for most owners, despite the higher upfront cost . If you are not experienced with automotive repairs, this is not a DIY job unless you are prepared for a full day of work and the potential for complications .

How a Fuel Pump Replacement Is Performed

When a mechanic replaces the fuel pump on a 2010 Acura TL, the first step is to disconnect the battery to reduce the chance of a fire . For pumps inside the fuel tank, there is usually an access cover that needs to be removed . With the cover off, the technician can replace the pump and pre-pump filter screen . In some cases, fuel will need to be drained before removing the access panel . Once the pump is replaced, another check is done to ensure there are no fuel leaks and that the problem is solved .

Most professional shops will also check the fuel filter, as well as the electrical and mechanical condition of the fuel pump itself, to verify the pump is the actual problem before replacing it . A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump . Have the shop verify that the pump is the problem before paying for replacement .

Preventing Premature Fuel Pump Failure

While fuel pumps eventually wear out, you can extend the life of your 2010 Acura TL fuel pump with good habits. Avoid running the fuel tank low on a regular basis, as the pump relies on fuel for cooling and lubrication . Replace the fuel filter according to the manufacturer's maintenance schedule to keep debris out of the pump . Use quality fuel from reputable stations to minimize contamination. If you notice any symptoms of a failing pump, address them early to avoid being stranded .
