2006 Toyota Vitz/Yaris fuel pump — what it does and when to service it

According to Toyota’s technical literature for the XP90 platform — including the New Car Features guide, the Repair Manual (Engine/EFI sections) and the Toyota Electronic Parts Catalogue — every 2006 Toyota Vitz/Yaris petrol variant (1KR‑FE, 2SZ‑FE, 1NZ‑FE) runs an in‑tank electric fuel pump module, listed as the “Pump Assy, Fuel Tank” with VIN‑specific part numbers in the 77020‑xxxxx range. So yes, a fuel pump is absolutely fitted and is essential to how this car runs.

The fuel pump’s job is pretty straightforward: it draws petrol from the tank and supplies steady pressure to the injectors, typically around 300–350 kPa at the rail as specified in the Toyota Repair Manual. On this model it’s a returnless system, with the pressure regulator and fine filter integrated into the pump module to reduce vapour and heat. No pump, no go — the engine will crank but won’t fire, or it’ll stumble and cut out under load.

For routine servicing, there’s no scheduled replacement interval for the pump itself. Toyota designed the module as “lifetime” under normal conditions. That said, a bit of care goes a long way:

• Try not to run the tank near empty
