Last month, we discussed the operation of the fuel system and a couple of emission systems that are related to this fuel system and how the Evaporative Emissions System works. Your vehicle's computer is programmed to warn of any type of leak in this system. A loose gas cap or a pin-sized hole in one of the lines can cause your check engine light to illuminate. The computer will store the code indicating that a leak is recognized, but then it needs to be located and repaired.

The best way to maintain your fuel system is listed below:

Keep the fuel tank level at ¼ of a tank or above. Most fuel pumps in newer vehicles are located in the fuel tank and it can cause some extreme wear to run the vehicle very low or out of fuel often.

If your vehicle has an in-line fuel filter, replace it about every 15,000 miles or annually. A plugged fuel filter can cause a restriction that can damage the fuel pump.

Have the fuel system cleaned every 2 years or 20,000 to 30,000 miles to keep the fuel injectors clean. This helps lower emissions, increases the longevity of the fuel injectors and improves performance and gas mileage.

If your check engine light comes on, have it diagnosed and repaired ASAP.

Maintaining the fuel system of your vehicle is pretty simple and fairly inexpensive. Having a professional with the proper equipment perform these services are crucial in the maintenance of todays vehicles. Happy Motoring!
