Fuel Delivery and Air Induction: Description and Operation

DESCRIPTION

The Fuel Delivery System consists of the following components:

- Fuel tank
- Fuel tank filler tube
- Tubes/lines/hoses
- Fuel rail

Fuel Tank





The fuel tank is made from High Density Polyethylene (HDPE) material and is located near the rear center of the vehicle. The primary fuel pump module is located on the top left side of the fuel tank. The fuel tank contains the following components:

- Fuel pump module
- Fuel tank vent (check valve)
- Control valve
- Inlet check valve

The Fuel pump module is the only serviceable component of the fuel tank. If the fuel tank vent, control valve or inlet check valve requires service, the fuel tank must be replaced as an assembly.

The fuel tank vent, control valve and inlet check valve are components of the evaporative emissions system.

Fuel Pump Module





The fuel pump module is mounted on the top of the fuel tank and contains the following components:

- Mounting flange
- Electric fuel pump
- Fuel pump reservoir
- Inlet strainer
- Fuel pressure regulator
- Fuel level sending unit
- Fuel filter

The electric fuel pump (2) is a positive displacement, immersible pump with a permanent magnet electric motor capable of creating 860 kPa (125 psi) of operating pressure. The fuel pressure regulator limits fuel pressure to 400 kPa (58 psi).

The fuel level sending unit (3) is the only serviceable component of the fuel pump module. If the electric fuel pump, fuel pressure regulator or fuel filter requires service, the fuel pump module must be replaced as an assembly.
