2007 Acura TL Fuel Pump Location: A Complete Owner's Guide

If you own a 2007 Acura TL and suspect a fuel pump issue, here's the direct answer: the fuel pump is located inside the fuel tank, and you can access it through an access panel under the rear passenger seat cushion. You do not need to drop the fuel tank to reach it on this model. This guide walks you through exactly where to look, how to confirm the pump is the problem, and what it costs to replace it.

Where Exactly Is the Fuel Pump on a 2007 Acura TL?

On the 2004-2008 third-generation Acura TL, the fuel pump module sits inside the fuel tank, which is mounted under the rear seat area. To get to it, you remove the rear seat cushion and lift a small access panel in the floor pan. This is a convenient design that saves hours of labor compared to older vehicles that require dropping the entire fuel tank.

For 2007 models specifically, you're working under the rear passenger side seat. Once the cushion is out, you'll see a metal or plastic cover plate held by a few screws or clips. Remove that plate, and the fuel pump module—a round assembly with electrical connectors and fuel lines on top—is right there.

The 2007 TL is part of the third generation (2004-2008), and access is under the rear seat. This applies to both the standard 3.2L V6 and the Type-S 3.5L V6 models, though the pump assemblies themselves differ by engine.

Symptoms of a Failing Fuel Pump

Before you start pulling seats and panels, make sure the fuel pump is actually the culprit. Here are the most common warning signs:

1. Engine cranks but won't start. The pump isn't delivering fuel pressure to the rail.
2. Loud whining noise from the rear of the car. A healthy pump runs quietly. A constant, loud hum or whine usually means the pump motor is straining or bearing wear is advanced.
3. Sputtering or surging at highway speeds. Inconsistent fuel delivery causes the engine to hesitate or lose power momentarily.
4. Loss of power under acceleration or on hills. The pump can't keep up with demand.
5. Poor fuel economy. A failing pump may push excess fuel or run erratically, hurting mileage.

On the 2005-2007 TL, there is also a known issue with the fuel pump relay, not the pump itself. Many stalling and no-start complaints on these years trace back to the relay, which is a much cheaper and easier fix. If your car dies suddenly and won't restart but the pump primes after cooling down, check the relay first.

How to Access the Fuel Pump Step by Step

Replacing the fuel pump on a 2007 TL is a DIY-friendly job for someone with moderate mechanical skills. Plan for about 1-2 hours. Here's the process:

Step 1: Relieve Fuel Pressure. Remove the fuel pump fuse from the under-hood fuse box, then crank the engine until it stalls. Turn the ignition off and reinstall the fuse. This releases pressure in the fuel lines so you don't get sprayed with gasoline.

Step 2: Disconnect the Battery. Always disconnect the negative battery cable before working near fuel or electrical connectors.

Step 3: Remove the Rear Seat Cushion. The bottom cushion pulls up and out. There are two clips near the front edge; press them and lift. For the 2007 TL, you don't need to remove the seat back, just the bottom cushion.

Step 4: Lift the Access Panel. Under the cushion, locate the round or rectangular metal cover plate over the fuel pump. Remove the screws or bolts, then lift the plate off.

Step 5: Disconnect Fuel Lines and Electrical Harness. Note the orientation of the quick-connect fittings. Use a shop rag to catch any residual fuel. Press the release tabs and pull the lines off. Unplug the electrical connector from the top of the pump module.

Step 6: Remove the Pump Module. The module is held by a large locking ring or nut. You'll need a fuel pump wrench or a brass punch and hammer to rotate it counterclockwise. Lift the assembly straight out of the tank. The float arm is fragile, so be careful not to bend it.

Step 7: Install the New Assembly. Lower the new pump module into the tank, making sure the float arm has clearance and the gasket sits flat. Reinstall the locking ring and tighten it securely. Reconnect the fuel lines and harness.

Step 8: Test. Reconnect the battery, turn the key to the ON position without starting, and listen for the pump to prime. Check for leaks at all connections, then start the engine.

Should You Replace Just the Pump Motor or the Whole Assembly?

Always replace the entire fuel pump module assembly, not just the pump motor. Here's why:

1. The plastic housing becomes brittle over time. A cracked housing can leak fuel—a serious fire hazard.
2. The integrated fuel strainer (filter sock) is a wear item. It's inside the tank and must be replaced with the pump.
3. The fuel level sending unit is part of the module. If it fails later, you'll be pulling everything apart again just to fix the gas gauge.
4. The assembly includes the pressure regulator on many models. Replacing the full module ensures all components are new and working together.

Most aftermarket pumps for the TL come as a complete module with the pump, sending unit, strainer, and sometimes the regulator. This is the recommended route for a reliable repair.

Replacement Cost for a 2007 Acura TL Fuel Pump

Here's what you can expect to pay in the U.S. market:

Used OEM pump assemblies are also available for around $65, and some owners prefer this route for original durability at a lower price. If you go this route, inspect the connectors for corrosion, the housing for cracks, and the fuel line fittings for damage before buying.

For the 2007 TL specifically, there are two common configurations:

1. 3.2L V6 (base model): The OEM part number is 17045-SEP-A50. This is the standard module assembly.
2. 3.5L V6 (Type-S, 2007-2008): Aftermarket options like the US Motor Works module (part 25677-03488331) or the Delphi DEFG1042 fit this engine. The Delphi unit includes the float arm, seal, lock ring, and strainer, and operates at 58 psi with a 12-volt supply.

The fuel system on the 2007 TL runs at approximately 45 psi at idle and up to about 58 psi under load, so make sure the replacement pump is rated for those pressures.

Tools You'll Need

You don't need anything exotic:

• Socket set and ratchet
• Screwdrivers (flathead and Phillips)
• Fuel pump lock ring wrench (or brass punch and hammer)
• Shop rags and a small container for leftover fuel
• Safety glasses and chemical-resistant gloves

Work in a well-ventilated area, away from open flames or ignition sources. Gasoline vapors are highly flammable.

Common Mistakes to Avoid

1. Not relieving fuel pressure first. This is the #1 cause of fuel spray and potential fires. Always follow the fuse removal procedure or use a fuel pressure gauge to bleed the system.
2. Damaging the float arm during installation. It's easy to bend when lowering the module into the tank. A bent arm gives inaccurate gas gauge readings.
3. Forgetting to check the fuel pump relay. On the 2007 TL, a faulty relay can mimic a dead pump. Test the relay before buying a pump, as it's a $20 part versus a $200+ module.
4. Buying the wrong pump for your engine. The base 3.2L and Type-S 3.5L use different pump assemblies. Double-check your engine size and VIN before ordering.
