Parts for your 2019 Toyota Hiace-Fuel pump

2019 Toyota HiAce fuel pump — what it does and how to look after it

Technical service literature confirms that a fuel pump is fitted to the 2019 Toyota HiAce, so it’s absolutely relevant for servicing and repairs. Toyota’s repair manuals for the H300 HiAce describe the diesel common-rail system (1GD-FTV) with a DENSO engine-mounted high‑pressure “supply pump”, and the petrol V6 (7GR‑FKS) D‑4S system with both an in‑tank electric pump and an engine‑mounted high‑pressure pump. The Toyota Electronic Parts Catalogue also lists a fuel tank module (fuel suction tube with pump and gauge assembly) on relevant variants. DENSO common‑rail technical guides cover the HP‑series supply pumps used on Toyota 1GD engines, while Toyota’s 7GR‑FKS system description details the in‑tank and high‑pressure pump arrangement for D‑4S.

On the diesel HiAce, the high‑pressure pump draws fuel through the filter, pressurises it for the rail, and precisely meters feed to the injectors. Depending on market spec, an in‑tank lift pump may be integrated with the tank sender module
