2003 Toyota Avensis fuel pump – what it does and when to service or replace it

Technical sources confirm a fuel pump is used on the 2003 Toyota Avensis. The Toyota Avensis T25 service and electrical wiring documentation list an electric in‑tank fuel pump for petrol engines (3ZZ‑FE 1.6, 1ZZ‑FE 1.8, and 1AZ‑FSE 2.0 D‑4), controlled via the circuit opening relay. The Toyota Electronic Parts Catalogue for T25 petrol variants shows a “fuel pump assembly (with filter/strainer)”. For the D‑4D diesels (2.0), Toyota workshop literature and the Haynes Toyota Avensis (2003–2008) manual describe an engine‑driven high‑pressure supply pump
