Parts for your 2008 Toyota Wish-Fuel pump

2008 Toyota Wish fuel pump — what it does and how to look after it

Based on Toyota’s technical literature, the 2008 Toyota Wish absolutely uses a fuel pump. The Toyota Electronic Parts Catalogue lists a fuel pump assembly for 2008 Wish models (ZNE10/ZNE14 1ZZ‑FE and ANE10 1AZ‑FSE). The Toyota Repair Manual and Electrical Wiring Diagram describe an in‑tank electric pump and module. For the 1AZ‑FSE D‑4 direct‑injection engine, Toyota’s New Car Features documentation also details a cam‑driven high‑pressure pump on the cylinder head that’s fed by the in‑tank pump. So, regardless of variant, a fuel pump is relevant and fitted to the 2008 Wish.

On this model, the in‑tank electric fuel pump’s job is to deliver a steady supply of petrol at the right pressure to the engine. In the 1ZZ‑FE (port injection), that’s the sole pump. In the 1AZ‑FSE (D‑4), it feeds a mechanical high‑pressure pump that ramps pressure up for direct injection. Either way, the pump is the quiet achiever that keeps cold starts crisp, highway overtakes smooth, and fuel economy on song.

There’s no scheduled replacement interval for the pump
