Your car's fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions.  check your car's fuel system regularly or immediately if you smell gas or suspect a problem.

The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for cleaning 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 into the engine.  Some vehicles use a return line system to return unused fuel back to the tank

intervals for fuel system maintenane may be influenced by:

• Fuel quality
• Vehicle age
• Mileage/time
• Operating conditions
• Maintenance history

Symptoms are poor fuel economy, Vehicle won't start and "check engine" light is illuminated.

It's best to replace your car's fuel filter every two years or 24,000 miles.
