  • All Your Fuel System Questions Answered

    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.

    What does it do? - The 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 vehicles use a return line system to return unused fuel back to the tank.

  • How is the Air Quality in Your Vehicle?

    When driving around town, your vehicle's engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Harold's Used Auto Parts Inc in Philadelphia, we want to help you get the best air quality in your vehicle, but first, we want to explain the process of where this dirty air is going.
