3 Best Practices to Maintain Your Vehicle's Fuel System

The fuel system within your automobile is usually either mechanical or electronic. Most of today's vehicles are equipped with an electronic fuel system. The fuel system usually comprises the fuel tank, pump, filter, and injectors or carburetor. 

  • The fuel pump is needed to pressurize fuel from the gas tank and deliver it to the engine. 
  • In an electronic fuel system, fuel injectors eject fuel into the motor's combustion chambers. The car's computerized system manages this process along with the position of the throttle, the air-fuel ratio, and the exhaust byproducts.
  • The fuel pump is electronically controlled to obtain the fuel from the tank and deliver it throughout the system. You can find it inside or next to the fuel tank.
  • The fuel filter filters out dust and debris from the fuel, so it does not get into the engine. These contaminants can sometimes get picked up when the gasoline moves from different areas. 

The best way to care for your fuel system and its components is by making the following efforts:

  • Replace your fuel filter on time and according to your manufacturer's recommended intervals.
  • Keep the fuel system clean by having the throttle body and fuel injection system cleaned professionally (~20,000 to 30,000 miles). This type of job is not recommended to do at home.
  • Don't let your fuel levels get too low, or else it can harm the fuel pump. A good rule of thumb to follow is not letting your tank fall below a quarter of the tank.

Following these maintenance tips can help your engine attain a proper air-fuel ratio mixture and reduce strain on your fuel system parts. Furthermore, your car will run more efficiently with better mileage and fewer emissions. Lastly, these tips can also prevent you from dealing with inconveniences like a breakdown.
