Fuel System & Economy

The Fuel System & Economy

The fuel system in your vehicle works with the rest of the engine control  system to deliver the maximum performance with the lowest emissions.  It transfers fuel from the fuel tank, passes it through a fuel filter for cleaning before it arrives at the  injectors. 

A pressure regulator controls the fuel pressure to ensure proper engine performance under a variety of speeds and load conditions. When activated the fuel injectors spray a metered amount of fuel into the engine. 

Many fuel systems have a return fuel line to return unused fuel back to the tank. We inspect the fuel line for signs of wear or damage during routine services.

Recommended Service

  • Inspect the air filter at every oil change.  Replace the air filter once a year or when torn, water or oil soaked, dirty or showing other signs of wear.
  • Every 30,000 miles a fuel system service should be performed to clean out the debris and carbon build up. This includes an induction cleaning service along with cleaning the intake and throttle plates.
  • Inspect the tire pressure monthly.  Tires that are under-inflated and lead to higher fuel costs.
  • Don't fill up if you see the tanker at the gas station. As the station’s underground tanks are being filled, the turbulence can stir up sediment. Sediment in your gas can clog fuel filters and fuel injectors, causing poor performance and possibly necessitating repairs.
  • Do fill up before your gas gauge reads empty or the low fuel light comes on. When your gas tank is too low it causes your fuel pump to work harder than it need to which can cause damage and create an expensive repair.
