2010 Acura TSX Fuel Pump: Complete Replacement Guide, Symptoms, and Costs
The bottom line up front: If you own a 2010 Acura TSX, the fuel pump is an in-tank electric module that sits inside the fuel tank, and when it starts failing, you will notice hard starting, hesitation during acceleration, and a whining noise coming from the rear of the car. A genuine OEM replacement part (17045-TA0-A00) costs between $395 and $462 from online Acura parts dealers, while a complete professional replacement job, including labor, typically lands in the $1,360–$1,404 range according to RepairPal estimates. The good news is that many owners choose a quality aftermarket option like Delphi or KEMSO and do the swap themselves in a weekend, saving a few hundred dollars in labor costs.
This guide breaks down everything about the 2010 Acura TSX fuel pump, including how to spot the early warning signs, which OEM and aftermarket part numbers fit your car, how much you should expect to pay for parts and labor, and step-by-step considerations for the replacement process.
1. Why the 2010 Acura TSX Fuel Pump Needs Attention
The 2010 Acura TSX with the 2.4L four-cylinder engine uses a fuel pump module assembly that is mounted inside the fuel tank. This module is not just a simple pump—it houses several critical components in one unit. According to Delphi's specifications, the fuel pump module assembly includes the pump itself, the fuel level sending unit (float arm), the fuel pressure regulator, the strainer, seals, and the lock ring. Everything works together to deliver fuel at the proper pressure to the engine while also telling your dashboard gauge how much fuel is in the tank.
Because all these parts live inside the fuel tank, they are subjected to heat, vibration, and the quality of fuel you put in the car. Over time, the pump's internal turbine and motor brushes wear out. When the pump cannot maintain the correct pressure—typically around 58 psi for this application according to Delphi's documentation—the engine starts showing the classic fuel starvation symptoms.
The 2010 model year falls within the 2009–2014 generation of the TSX, and the OEM part number for the 2.4L model is 17045-TA0-A00. This same part number covers the 2009 through 2014 model years with the four-cylinder engine, which means your 2010 TSX uses the exact same fuel pump assembly as later models in that generation. That is worth knowing if you buy a used part or cross-reference a replacement.
For the 2.4L engine, there is also an alternative OEM part number 17045-TP1-A00, but that one is for the 3.5L V6 model of the TSX (2010–2014), not the four-cylinder. So when you shop, you must be careful to select the correct one for your engine.
2. Six Warning Signs Your 2010 Acura TSX Fuel Pump Is Failing
Recognizing the early signs of a failing fuel pump can save you from being stranded on the side of the road. AutoNation Mobile Service lists six common symptoms that point to a bad fuel pump:
1. Whining or sputtering sounds from the fuel tank. If you hear a high-pitched whine coming from the rear of the car, especially when the engine is running, the pump may be struggling. The noise happens because the pump motor is working harder than it should. If you also hear sputtering or backfiring, that is a stronger indication that fuel pressure is dropping off inconsistently.
2. Difficulty starting the car. A weak fuel pump cannot build up enough pressure in the fuel line to get the engine going. You might find yourself cranking the engine longer than normal, or needing two or three attempts before it fires up. In the worst cases, the car may refuse to start altogether.
3. Hesitation, surging, or loss of power. When you press the accelerator, the engine may hesitate or feel like it is losing power. This happens because the pump is not delivering a steady, adequate flow of fuel, especially when you are asking for more power during acceleration or uphill driving. Some drivers describe it as feeling like the car is running out of gas even when the tank is full.
4. Rough idle and misfiring. An inconsistent fuel supply throws off the air-fuel ratio in the engine. This can cause the engine to idle roughly or misfire. Over time, the poor combustion will reduce your fuel economy noticeably.
5. Overheating and sudden stalling. A worn pump can overheat, especially during extended drives. Many drivers report that the car runs fine for the first 15 to 30 minutes, then suddenly stalls. After the pump cools down, the car starts again, only to repeat the cycle later.
6. Low fuel pressure readings. If you hook up a fuel pressure gauge to the service port, the reading will be below the factory specification. Delphi's documentation lists the system pressure for this fuel pump module at 58 psi, with a maximum pressure rating of 78 psi. If your readings fall well below 58 psi, the pump or the pressure regulator is failing.
3. Which Fuel Pump Fits the 2010 Acura TSX: OEM vs. Aftermarket
When it comes to replacing the fuel pump on your 2010 TSX, you have several reliable options. Below is a breakdown of the most common part numbers and what they include.
3.1 Genuine Acura OEM Fuel Pump (Part Number 17045-TA0-A00)
The genuine Acura part is the direct replacement for your 2010 TSX 2.4L. It is sold as a "Module Set, Fuel Pump" and includes the sending unit (fuel level float). The factory warranty covers genuine parts, and they are designed to match the original fit and function exactly. Online Acura parts retailers sell this part for roughly $395 to $462, with a manufacturer's suggested retail price (MSRP) of $577.55. If you go to a dealership parts counter, expect to pay closer to full MSRP. This option is ideal if you want the same part that came from the factory and you prefer zero guesswork.
3.2 Delphi Fuel Pump Module (Part Numbers FG0962 and FG0912)
Delphi is a well-known aftermarket manufacturer that supplies original equipment to automakers. Their FG0962 fuel pump module assembly is a direct-fit replacement for the 2010–2014 Acura TSX 2.4L, as well as other Honda and Acura models like the 2008–2014 Honda Accord. This module includes the fuel level sender assembly, regulator, strainer, gasket or seal, and lock ring, so it is a complete tank-side repair kit.
Delphi specifies an average flow rating of 21 gallons per hour and an average current draw of 11 amps for this module. The operating system pressure is 58 psi, and the maximum pressure rating is 78 psi. The fuel level sender resistance is 780 ohms when empty and 20 ohms when full, which matches the factory gauge calibration.
There is also the Delphi FG0912 module, which is sold specifically for the 2009–2014 Acura TSX 2.4L 4-cylinder engine (2354cc). This version has a maximum pressure rating of 65 psi and a minimum of 51 psi, which is slightly different from FG0962. Both are premium-grade replacements, and either one will work in your 2010 TSX. The FG0912 carries an RRP of about $486.95, though online retailers often discount it to around $404.
3.3 Other Aftermarket Options (Airtex, Carter, Spectra Premium, ECCPP)
Several other brands make direct-fit fuel pumps for the 2010 Acura TSX. According to one parts listing, the Airtex E8922M, Carter P76709M, and Spectra Premium SP8005M all cross-reference to the same application. The ECCPP brand module, for example, lists a flow rate of 50–60 gph and a pressure range of 45–55 psi, which is within the acceptable operating window for this engine. These are budget-conscious alternatives, but it is worth noting that warranty coverage and build quality can vary more between brands than with OEM or Delphi.
3.4 Delphi FG0962 Cross-Reference Information
If you are comparing prices online, you may notice that some fuel pumps are listed as cross-references to a Delphi part. The Delphi FG0962 cross-references the Carter P76708M for the same application. The OEM part number 17045-TA1-L00 is also mentioned as a cross-reference for the same family of vehicles. This is useful because it gives you more search terms to use when hunting for competitive pricing.
4. How Much Does a 2010 Acura TSX Fuel Pump Replacement Cost?
Understanding the full cost picture helps you budget. Here is how the numbers break down.
4.1 Parts-Only Cost
| Part Option | Price Range |
|---|---|
| Genuine Acura OEM (17045-TA0-A00) | $395 – $462 |
| Genuine Acura OEM MSRP | $577.55 |
| Delphi FG0912 (premium aftermarket) | ~$404 – $487 |
| Delphi FG0962 (cross-reference) | Not listed but comparable |
| Budget aftermarket (ECCPP, Airtex, etc.) | ~$50 – $150 |
If you are doing the job yourself, the parts cost is the main expense. A DIY replacement guide for the 2011 and 2014 Acura TSX estimates that a DIY fuel pump replacement costs approximately $50 to $300 in parts. That lower figure is achievable if you purchase a budget aftermarket brand; the higher figure aligns with Delphi or OEM pricing.
4.2 Professional Labor Cost
If you decide to pay a shop to do the work, labor will add significantly to the bill. RepairPal estimates the average total cost for an Acura TSX fuel pump replacement (parts plus labor) at $1,360 to $1,404. This estimate is based on national averages, so your actual cost may vary depending on your location, the shop's hourly rate, and whether the mechanic needs to drop the fuel tank or access the pump through a panel.
For the 2.4L engine, the access cover is located in the rear of the vehicle, and the pump is mounted in the tank. Removing the fuel tank is not always necessary, but the job does require some care with fuel lines and electrical connectors.
4.3 DIY Cost Savings
Performing the replacement yourself can save you roughly $100 to $400 compared to having a professional do it. The DIY guide for the 2014 TSX specifically notes that a DIY replacement saves you approximately $100–$400 in labor costs. The job usually takes 1 to 3 hours for a first-timer, depending on your level of experience and whether you have to deal with a full fuel tank.
5. Step-by-Step Overview of the Fuel Pump Replacement Process
While the full procedure is best done with a factory service manual, here is a high-level overview of what the replacement involves.
1. Disconnect the battery. This reduces the risk of sparks igniting fuel vapors. Always start any fuel system work this way.
2. Relieve fuel system pressure. Remove the fuel pump fuse and run the engine until it stalls, or disconnect the fuel line carefully with a shop rag to catch any pressurized fuel.
3. Remove the rear seat or access panel. On the TSX, there is an access cover under the rear seat that lets you reach the fuel pump without dropping the tank in most cases.
4. Disconnect the electrical connector and fuel lines. Mark the lines so you know which one goes where during reassembly.
5. Remove the lock ring. This requires a special tool or a brass punch and hammer. The lock ring holds the pump module in place on top of the tank.
6. Lift out the old pump module assembly. Be careful not to bend the float arm. The fuel level sender (float) is part of the module, so it comes out together.
7. Transfer any reusable components. If your replacement module does not come with a new lock ring or seal, transfer the old ones after cleaning them.
8. Install the new pump module assembly. Drop it straight in, align the float arm, replace the lock ring, and reconnect the fuel lines and wiring harness.
9. Reinstall the access cover and seat.
10. Turn the key to the ON position (without starting), let the pump prime, and check for leaks before starting the engine.
One important tip from Delphi: always clean the fuel tank before installing a new pump to reduce the risk of contamination-related failure. Delphi recommends using fuel tank cleaning kit FC01 in these applications.
6. Frequently Asked Questions About the 2010 Acura TSX Fuel Pump
6.1 What is the OEM part number for the 2010 Acura TSX 2.4L fuel pump?
The OEM part number is 17045-TA0-A00. This part is used on the 2009–2014 Acura TSX base model with the 2.4L four-cylinder engine. It includes the fuel pump and the sending unit.
6.2 Is the fuel pump the same as the sending unit?
No, but they are often sold together. The genuine Acura part (17045-TA0-A00) is described as a "Module Set, Fuel Pump" and includes the sending unit. Delphi's module also includes the fuel level sender assembly. If you buy a bare pump without the sending unit, you will need to transfer the old float arm and sender assembly, which is possible but more labor-intensive.
6.3 How often should I replace the fuel pump on my TSX?
There is no fixed service interval for fuel pumps. They are expected to last the life of the vehicle, but typical replacement intervals fall between 100,000 and 150,000 miles. Heat, contaminated fuel, and low fuel levels (which cause the pump to run hotter) can shorten the lifespan.
6.4 Can I drive with a failing fuel pump?
AutoNation Mobile Service addresses this question and recommends against it. Driving with a failing fuel pump can cause engine stalling, which is dangerous in traffic. It also risks damaging other fuel system components, such as the fuel filter, which can clog with debris from the failing pump. Once the pump stops entirely, the car will not start, and you could be stranded.
6.5 Does the 2010 Acura TSX have a fuel filter in the tank?
Yes, the fuel pump module includes an internal strainer, and the vehicle also has a fuel filter in the system. Delphi's module lists "Fuel Filter Included: Yes" in its specifications, and the strainer is internal. Replacing the fuel pump module typically includes the filter and strainer, which is another reason why a complete module swap is recommended over a bare pump replacement.
