Fuel Delivery System

Description:

DESCRIPTION
The function of the fuel system is to deliver the correct amount of fuel to the engine under all operating conditions. Fuel is stored and supplied by the fuel supply system and delivered by the fuel injection system. The fuel injection system is controlled by the Powertrain Control Module (PCM).

FUEL SYSTEM COMPONENTS
The fuel system consists of the following components:

- Fuel tank.
- Fuel sender with strainer
- Fuel lift pump.
- Fuel manager/filter.
- Fuel pipes and hoses.
- Fuel injection system components.

- Electronic fuel injection pump with PCM controlled solenoids and PCM sensors.
- High pressure injection lines.

- Injection nozzles.
- Fuel return system.
- Accelerator control system.

FUEL SUPPLY SYSTEM
The fuel supply is stored in the fuel tank. Fuel is drawn from the fuel tank by the fuel lift pump. Fuel is then pumped through the fuel manager/filter. The fuel manager/filter is located on the intake manifold. The fuel is then transferred to the injection pump. Unused fuel is returned to the fuel tank by a separate line.
