Where is the fuel pump located in a 2005 Honda Accord?

The fuel pump is located inside the fuel tank; access is gained through a circular panel beneath the rear seat cushion, not from the engine bay.

In a 2005 Accord, the pump is an in-tank unit that sits on top of the fuel tank. Access to service it is provided by an access panel under the rear seat. This setup is consistent across sedan and coupe body styles for that model year, though exact seat-removal steps can vary by trim.

Location and access basics

All 2005 Accords use an in-tank fuel pump. The top of the tank houses the pump, and there is a circular access panel under the rear seat cushion that must be removed to reach it. The rear seat assembly must be moved or removed to access the panel and pump.

Notes on model variations

While the general arrangement is the same for sedan and coupe, the exact steps to remove the rear seat cushion and locate the panel may differ slightly by trim level or market. Always consult the owner’s manual or a service guide for your specific vehicle.

Before attempting any work, understand safety considerations: relieve fuel pressure, disconnect the battery, work in a well-ventilated area away from sparks or flames, and avoid open flames.

Step-by-step access and safety tips

To inspect or replace the pump, follow these steps. They assume basic hand-tool ability and proper safety precautions.

1. Park on a level surface, set the parking brake, and disconnect the negative battery cable to prevent sparks.


2. Relieve fuel pressure: remove the fuel pump fuse/relay, then crank the engine with the ignition on to bleed pressure; turn off after the engine stalls.


3. Remove the rear seat cushion to expose the access panel beneath it. Lift from the front edge and pull up to release.


4. Remove the circular access panel screws or clamps and lift the cover to expose the pump module.


5. Disconnect the fuel line and electrical connector from the pump module carefully to avoid damaging the line or O-ring seal.


6. Remove the pump assembly from the tank, inspect or replace it, and ensure the O-ring seal is in good condition.


7. Reinstall the pump, reseat the access panel, reinstall the seat cushion, reconnect the battery and fuel lines, and turn the ignition to verify proper fuel pump operation.

After completing, check for leaks and proper operation. If you're unsure, consult a professional.

Summary: For a 2005 Honda Accord, the fuel pump is an in-tank unit accessed via a rear-seat panel under the cushion. With proper safety steps, you can inspect or replace it by removing the rear seat and the circular access cover, then reassembling and testing the system.
