Parts for your 2018 Toyota Crown-Fuel pump

2018 Toyota Crown fuel pump — what it does and how to look after it

Yes, the 2018 Toyota Crown uses a fuel pump. Technical references including Toyota’s Repair Manual and New Car Features for the Crown, plus the Toyota Electronic Parts Catalogue (EPC) listing the in‑tank “Fuel Pump Assembly (77020‑xxxxx)” for 2018 S210/S220 models, confirm its fitment. On petrol Crowns with D‑4S or D‑4ST injection (such as the 2.0‑litre turbo and some V6 hybrids), there’s also an engine‑mounted high‑pressure pump fed by the in‑tank electric pump. Toyota wiring diagrams and service literature for the 2018 Crown further describe ECM‑controlled pump operation for pressure and noise management. So the fuel pump is absolutely relevant on this model.

On a 2018 Toyota Crown, the in‑tank electric fuel pump’s job is simple but crucial: it lifts petrol from the tank and delivers it at steady low pressure to the rail (or to the engine’s high‑pressure pump on D‑4S/D‑4ST engines). That stable supply keeps starts crisp, throttle response sharp, and emissions in check. For turbo and hybrid variants with direct injection, the low‑pressure pump works in tandem with a cam‑driven high‑pressure pump that ramps pressure up for atomisation inside the chamber.

As for servicing, the fuel pump isn’t a scheduled replacement item
