Parts for your 2010 Toyota Aurion-Fuel pump

2010 Toyota Aurion fuel pump — what it does and when to replace it

Based on technical documentation, a fuel pump is absolutely fitted to the 2010 Toyota Aurion (GSV40R, 2GR‑FE 3.5‑litre V6). Toyota’s GSV40R Repair Manual (Fuel System, 2GR‑FE) and the Toyota Electronic Parts Catalogue list an in‑tank “fuel suction with pump assembly,” a returnless setup with an integrated pressure regulator and strainer. Trade guides covering Camry/Aurion 2006–2011 also show service access via the rear seat to the pump module. So yes—this model relies on an electric, in‑tank fuel pump.

On the Aurion, the pump’s job is to deliver steady fuel pressure from the tank to the port fuel injectors, typically around the 3–4 bar range as specified by Toyota. Being a returnless system, pressure is controlled in the tank module, which keeps heat and vapour formation down and helps emissions. The strainer and primary filter are built into the module, so they’re not regular service items on their own.

As part of routine servicing, most owners won’t need to touch the pump until there are symptoms. Running the tank low regularly, contaminated fuel, or simply high kilometres can wear the pump. Many last well past 200,000 km when fed clean petrol and the tank isn’t run near empty all the time.

• Common signs it’s on the way out: longer cranking, hesitation under load, a loud whining from the tank, surging at highway speeds, or lean fault codes.
• Good habits: use reputable fuel, avoid habitually driving on near‑empty, and keep the evap and tank venting in good nick.

When replacement is needed, the module is accessed under the rear seat base. No special coding is required on the Aurion—fit the new unit, reconnect, prime the system and check pressures and trims.

1. Disconnect the battery and safely relieve fuel pressure.
2. Lift the rear seat, remove the access cover, label fuel lines and the connector.
3. Undo the lock ring, lift the module, and swap the seal/gasket—always fit a new seal.
4. Seat the module squarely
