Car Fuel System

What is the car fuel system? – The fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. If you smell fuel or suspect a problem address this immediately.

What does the car fuel system do? – The car 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 into the engine.  Some cars use a return line system to return unused fuel back to the tank.

Wear & Tear on vehicle fuel systems, the intervals for fuel system maintenance may be influenced by fuel quality, vehicle age, mileage and time, operating conditions and maintenance history are all factors that affect this.

The fuel system includes: pressure regulator, fuel injectors, lines, hoses, fuel filter, fuel tank and fuel pumps.  Poor fuel economy, vehicle not starting, check engine light can all be symptoms of a fuel system problem.
