Parts for your 1999 Toyota Crown-Fuel pump

1999 Toyota Crown fuel pump

Based on Toyota technical literature for the S170-series Crown (1999) – including the Toyota Electronic Parts Catalog (EPC) for JZS17# models and the factory Repair Manual fuel section – this vehicle is equipped with a fuel pump. Petrol variants with conventional EFI use an electric in-tank pump, and D-4 direct-injection engines (e.g., 1JZ-FSE) use that in-tank pump as a lift/supply pump plus an engine-mounted high-pressure pump driven by the camshaft. So yes, a fuel pump is relevant and fitted to the 1999 Toyota Crown.

On the Crown, the pump’s day job is simple but critical: keep the fuel rail supplied at the right pressure so the engine runs smoothly, starts crisply, and delivers proper power and economy. For port-injected engines, the in-tank electric pump feeds the rail via the filter and regulator. For D-4 engines, the in-tank pump supplies low pressure to the mechanical high-pressure pump, which then boosts pressure for the direct-injection system. Either way, clean fuel and stable pressure are the goal.

There’s no fixed replacement interval for the in-tank pump
