2012 Toyota Avensis fuel pump — purpose, care, and when to replace

Technical sources confirm the 2012 Toyota Avensis does use a fuel pump. The Toyota Avensis (T27) Repair Manual and Electrical Wiring Diagram specify an in‑tank “fuel suction with pump” assembly for petrol models, while D‑4D diesels use a high‑pressure supply pump (HPFP) on the engine for the common‑rail system. Toyota’s Electronic Parts Catalogue lists these assemblies for 2012 Avensis variants, and general guides like the Haynes Avensis manual and Bosch common‑rail literature back this up.
