What does it do?

The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors.

A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions.

Fuel injectors, when activated, spray a metered amount of fuel in to the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Typical wear and tear

Intervals for fuel system maintenance maybe influenced by:

• Fuel quality;
• Vehicle age;
• Mileage/time;
• Operating conditions; and/or
• Maintenance history.

Symptoms

• Poor fuel economy;
• Vehicle won’t start; and/or
• “Check Engine” light is illuminated.

Maintenance

We recommend the following preventative maintenance service for your vehicle's fuel system:

• Fuel filter replacement every 50,000 KM or at least every 2 years; and
• Fuel Injection Service (engine decarbonization) every 25,000 KM or at least every 12 months.
