Purpose, Function
Supplies fuel in the fuel tank to the high pressure fuel pump.
Based on the control signal from the PCM, the fuel pump operates by the operation of the fuel pump relay and the fuel pump control module.
Construction
2WD
The fuel pump unit is installed to the fuel tank.

The fuel pump unit consists of a fuel pump, fuel filter (low-pressure) fuel filter (high-pressure), pressure regulator, and lower cover.

AWD
The fuel pump unit is installed to the fuel tank.

The fuel pump unit consists of a fuel pump, fuel filter (low-pressure) fuel filter (high-pressure), pressure regulator, lower cover, and jet pump.

Operation
2WD
Based on the control signal from the PCM, the fuel pump suctions fuel in the lower cover and pumps it to the high pressure fuel pump. After fuel is sufficiently filtered through the fuel filter (low-pressure) and fuel filter (high-pressure), fuel pressure is adjusted to approx. 430 kPa {4.38 kgf/cm2, 62.4 psi}
by the pressure regulator.

by the pressure regulator.

Positions the venturi pipe (jet pump) in the return path from the pressure regulator and sends fuel from the fuel tank sub side to the main side using vacuum generated in that area.

Returnless Fuel System
Purpose, Outline
Fuel evaporation in the fuel tank is reduced by adjusting the fuel amount
(fuel pressure) ejected from the fuel pump and preventing fuel warmed in the
engine compartment from returning.
