2008 Acura TL Fuel Pump: Complete Replacement Guide and Best Options
The bottom line up front: If you own a 2008 Acura TL and you are experiencing hard starts, sputtering under acceleration, or a whining noise coming from the rear of the car, the fuel pump is very likely the problem. Replacing the fuel pump module assembly on a 2008 Acura TL is a straightforward job that can be done at home, and the total cost for parts ranges from roughly $85 to over $500 depending on whether you choose an aftermarket, OEM, or performance-oriented replacement. Most owners can complete this repair in an afternoon with basic hand tools, and doing it yourself can save you $1,000 or more compared to dealer labor rates.
The 2008 Acura TL fuel pump is an in-tank electric unit that delivers fuel from the tank to the engine at a regulated pressure of 58 psi . Over time, the pump motor wears out, the fuel strainer clogs, or the sending unit fails, leading to a range of drivability issues. This guide walks you through everything you need to know about the 2008 Acura TL fuel pump: symptoms of failure, replacement cost breakdown, how to choose the right part, step-by-step installation instructions, and where to buy a reliable component. Whether you drive the base 3.2L V6 or the Type-S 3.5L V6, the information here applies to your car.
Symptoms of a Failing Fuel Pump in a 2008 Acura TL
A failing fuel pump in a 2008 Acura TL does not fail silently. The symptoms are usually noticeable long before the car completely stops running. Here are the most common signs to watch for:
1. Hard starting. If the engine cranks for several seconds before firing, or if it takes multiple attempts to start, the fuel pump may not be building enough pressure in the fuel lines.
2. Engine sputtering or surging at speed. A weak fuel pump cannot maintain a steady fuel supply at higher RPMs. You may feel the car hesitate, stumble, or momentarily lose power when you press the accelerator.
3. Loss of power under load or uphill. When the engine demands more fuel, a worn pump cannot keep up. This often shows up as a noticeable lack of power when climbing hills or merging onto a highway.
4. Whining noise coming from the fuel tank area. The fuel pump sits inside the fuel tank, which is located behind the rear seat and under the trunk floor on the 2008 TL. A loud, high-pitched whine that gets louder as you accelerate is a classic sign of a pump that is working too hard.
5. Check Engine Light with fuel system codes. A fuel pump that cannot produce adequate pressure will trigger diagnostic trouble codes related to fuel trim or fuel pressure. The car may also run rich or lean, which the engine computer detects.
6. Intermittent stalling. If the fuel pump motor is failing intermittently, the engine may shut off without warning, especially in hot weather or after the car has been driven for a while.
Keep in mind that a clogged fuel filter can produce identical symptoms. Before condemning the fuel pump, it is wise to have a shop check fuel pressure at the fuel rail. If the pressure is below spec, the pump itself is the likely culprit.
2008 Acura TL Fuel Pump Replacement Cost Breakdown
The total cost of replacing a fuel pump on a 2008 Acura TL varies widely based on where you buy the part and who does the work. Here is the realistic breakdown:
| Option | Part Cost | Labor Cost | Total Estimate |
|---|---|---|---|
| DIY with aftermarket pump | $85 – $240 | $0 | $85 – $240 |
| DIY with OEM pump | $344 – $550 | $0 | $344 – $550 |
| Professional shop (aftermarket) | $85 – $240 | $150 – $300 | $235 – $540 |
| Professional shop (OEM) | $344 – $550 | $150 – $300 | $494 – $850 |
| Dealership replacement | Covered above | $85 – $125 | $1,228 – $1,268 |
According to RepairPal, the average cost for a professional 2008 Acura TL fuel pump replacement is between $1,228 and $1,268, with labor estimated at $85 to $125 and parts priced around $1,143. That parts price reflects a dealer-sourced or OEM component. The same repair at a dealership will be at the top end of that range.
For owners who are comfortable turning a wrench, doing the job yourself with a quality aftermarket fuel pump module assembly brings the cost down to less than $250 in most cases. A brand-new aftermarket fuel pump assembly from brands like Delphi, Spectra Premium, or A-Premium typically costs between $85 and $240. Even the premium Delphi DFG0914 unit is available for around $220, which is roughly half what a dealer charges for the OEM part.
Labor costs at an independent shop usually run $150 to $300, depending on your location and the shop's hourly rate. This is a job that most shops quote at 1.5 to 2.5 hours of labor. Since the fuel pump is accessible through a panel in the trunk area, the shop does not need to drop the fuel tank, which keeps labor time reasonable.
The smart money move for most owners is to buy a quality aftermarket pump module and either install it yourself or hire an independent mechanic. You will receive a brand-new component that meets or exceeds OEM specifications, and you will save $800 to $1,000 compared to the dealership route.
OEM and Aftermarket Fuel Pump Options for the 2008 Acura TL
When it comes time to buy a replacement fuel pump for your 2008 Acura TL, you have three main categories to choose from: OEM genuine parts, premium aftermarket brands, and budget aftermarket parts. Each has its strengths, and the right choice depends on your budget and how long you plan to keep the car.
1. Genuine Acura OEM Fuel Pump (Part #17045-SEP-A01 and 17045-SEP-A50)
The original equipment part number for the 2008 Acura TL base model with the 3.2L V6 is 17045-SEP-A01, and it replaces the earlier 17045-SEP-A00. The Type-S model, which uses the 3.5L V6, uses part number 17045-SEP-A50. Both parts include the fuel pump module assembly, sending unit, pressure regulator, and filter. The OEM part is priced around $344 to $550 depending on the seller. Honda Acura Online lists the 17045-SEP-A01 at roughly $344, which is a discount off the MSRP of $496. The OEM part is guaranteed to fit perfectly and is backed by Acura's factory warranty. This is the safest choice if you want no guesswork and are willing to pay a premium.
2. Delphi Fuel Pump Module Assembly
Delphi is a Tier 1 supplier to global automakers, meaning they manufacture original equipment parts for car manufacturers. Their fuel pump module assemblies are built to OE standards and are a direct-fit replacement for the Acura TL. The Delphi DFG0914 part fits the 2004-2008 Acura TL 3.2L V6 and costs approximately $205 to $220. For the 2007-2008 Type-S with the 3.5L V6, the Delphi DFG1042 is the correct part, priced around $240.
Delphi pumps feature lower amperage draw, which reduces load on the vehicle's electrical system, and lower failure rates due to innovative design and durability improvements. The DFG1042 includes the fuel level sender assembly, regulator, strainer, gasket or seal, and lock ring—everything you need for a complete installation. The Delphi unit cross-references to OEM part numbers 17045-SEP-A50 and 17045-SDB-A00. With a lifetime warranty available from many sellers, this is the most popular aftermarket choice among Acura TL owners.
3. Spectra Premium and Other Budget Options
Spectra Premium offers two compatible fuel pump modules for the 2008 Acura TL. The SP1344 model (part #A1344EP) is priced at $186.99 and the SP8028M model (part #D8003M) at $221.99. The SP8028M is the correct cross-reference for the 3.2L base engine. These pumps come with a limited-lifetime warranty and are designed to meet OEM fit and function standards.
Another budget-friendly option is the A-Premium APFP0809, available for $84.99, which fits the 2007-2008 Acura TL with the 3.5L V6. It includes the sending unit and float, comes with a 3-year warranty, and is constructed to fulfill OEM criteria.
One important note: many sellers and manufacturers strongly recommend replacing the entire pump module assembly rather than just the pump motor itself. The module includes the strainer, sending unit, and plastic housing, all of which can wear out over time. Replacing the whole thing at once prevents you from having to open up the fuel tank again in six months when the sending unit fails.
Where Is the Fuel Pump Located on a 2008 Acura TL?
The fuel pump on a 2004-2008 Acura TL is located inside the fuel tank, which sits under the rear seat and behind the trunk area. Fortunately, you do not need to drop the fuel tank to access it. There is an access panel in the trunk floor, typically underneath the carpet and insulation, that gives you direct access to the fuel pump module.
Here is how to locate it:
1. Open the trunk and remove the spare tire cover and spare tire if present.
2. Remove the carpet and any sound-deadening material from the floor of the trunk.
3. You will see a metal or plastic access cover with a locking ring. This is the access panel to the fuel pump.
4. Remove the access cover to reveal the top of the fuel pump module assembly.
This design makes the 2008 Acura TL fuel pump replacement an easy DIY job, even for someone with basic mechanical experience.
Step-by-Step 2008 Acura TL Fuel Pump Replacement
Before you begin, gather the following tools and safety items: a set of sockets and ratchets, a flathead screwdriver, a fuel line disconnect tool (if needed), a drain pan, safety glasses, and gloves. Work in a well-ventilated area and never smoke or use an open flame near the fuel system.
Step 1: Relieve Fuel Pressure
The fuel system is under high pressure (58 psi at idle). To relieve it, remove the fuel pump fuse from the fuse box and crank the engine for a few seconds until it stalls. This lowers the pressure in the fuel lines. Once the engine stalls, turn the ignition off and reinstall the fuse.
Step 2: Disconnect the Battery
Disconnect the negative battery terminal to eliminate any chance of sparks while working around fuel.
Step 3: Access the Fuel Pump
Follow the steps above to remove the trunk access panel. Once the access cover is off, clean the area around the fuel pump flange with a shop towel to prevent debris from falling into the tank.
Step 4: Disconnect Fuel Lines and Electrical Connector
Use a fuel line disconnect tool to release the quick-connect fittings on the fuel supply line. You may also need to disconnect a return line if your vehicle has one. Then, unplug the electrical connector from the top of the pump module. Take note of the connector orientation and wiring.
Step 5: Remove the Lock Ring
The pump module is held in place by a large plastic lock ring. Use a flathead screwdriver and a hammer to tap the ring counterclockwise to unlock it. Turn it until it releases, then lift the lock ring off.
Step 6: Remove the Old Pump Module
Carefully lift the fuel pump module out of the tank. Go slowly and gently, as the float arm is fragile. Tilt the module to allow the fuel inside to drain back into the tank. Place the module in your drain pan to catch any remaining fuel.
Step 7: Install the New Pump Module
Before installing the new module, clean the fuel tank opening and inspect the inside of the tank for debris or sediment. If the tank is dirty, clean it out to prevent future clogging of the new pump. Place the new module into the tank, ensuring the float arm clears the bottom of the tank and the rubber seal sits evenly on the rim. Align the orientation tabs correctly.
Step 8: Secure the Lock Ring
Place the lock ring over the module and press it down. Use your flathead screwdriver and hammer to rotate the lock ring clockwise until it locks firmly into place. Do not overtighten—the ring only needs to be snug enough to compress the seal.
Step 9: Reconnect Everything
Reconnect the fuel lines by pushing the quick-connect fittings until they click. Plug in the electrical connector, ensuring the clip snaps into place. Reinstall the access cover, trunk carpet, and spare tire.
Step 10: Reconnect Battery and Test
Reconnect the negative battery terminal. Turn the ignition to the "ON" position for 2-3 seconds (without cranking), then off. Repeat this cycle two or three times to prime the fuel system. Then start the engine and check for leaks around the pump flange. Make sure the fuel gauge reads correctly and the engine runs smoothly.
What About the 2008 Acura TL Type-S Fuel Pump?
The 2008 Acura TL Type-S is equipped with a 3.5L V6 engine (J35A8), which is different from the base model's 3.2L V6. This means the Type-S requires a different fuel pump part number. The correct OEM part for the Type-S is 17045-SEP-A50.
If you shop aftermarket, use the following cross-reference numbers to find the right replacement:
| Brand | Part Number | Fits | Price Range |
|---|---|---|---|
| Delphi | DFG1042 | 2007-2008 TL Type-S, 3.5L | $239.99 |
| Spectra Premium | D8047M | 2007-2008 TL Type-S | $234.99 |
| A-Premium | APFP0809 | 2007-2008 TL Type-S | $84.99 |
| US Motor Works | USEP8567M | 2007-2008 TL Type-S | $187.97 |
Each of these modules is a complete assembly that includes the fuel pump, strainer, sending unit, and regulator. Double-check your vehicle fitment before ordering to ensure you get the correct part for your specific engine and submodel.

How to Verify Fitment Before You Order
No matter which brand you choose, the most important step is to verify that the fuel pump fits your specific vehicle. Acura built the 2008 TL in several configurations, and not every pump works with every car.
Here is how to make sure you order the right part:
1. Check your engine size. The base TL has a 3.2L V6 (J32A3), and the Type-S has a 3.5L V6 (J35A8). Use your VIN or the sticker under the hood to confirm.
2. Determine your body style and submodel. The TL comes in Base and Type-S trims for 2008.
3. Cross-reference the OEM part number. The base model uses 17045-SEP-A01. The Type-S uses 17045-SEP-A50.
4. If you are buying aftermarket, compare the interchange list. Most quality aftermarket pumps list the OEM part numbers they replace.
5. Input your year, make, model, and engine into the compatibility checker on the retailer's website before adding to cart.
A wrong fuel pump may physically fit but operate at the wrong pressure or have the wrong electrical connector, leading to drivability issues or a no-start condition. Always confirm fitment before ordering.
Final Thoughts on the 2008 Acura TL Fuel Pump

Driving with a weak fuel pump can damage your fuel injectors and catalytic converter over time, turning a $200 repair into a $1,500 one.
The good news is that this is a DIY-friendly repair that you can tackle in a few hours with basic tools. The fuel pump is conveniently located under the trunk floor, so there is no dropping the fuel tank. A quality aftermarket pump costs less than $250, and the OE-style replacement will give you years of trouble-free operation.
