Check Vehicle Fit

Dirt and even rust can enter the fuel stream at any point along the long journey from refinery to your vehicle’s fuel tank. So, your fuel filter becomes the final line of defense against damaging contaminants getting into your vehicle. Clean fuel, free from dirt particles and rust, is essential for the smooth and efficient operation of your vehicle. A tiny grain of dirt can clog injectors, leading to erratic performance and poor gas mileage. Clean fuel increases gas mileage and improves engine performance - and with the fluctuating cost of gas these days, that’s really important!

Product Features:
  • Defense against damaging contaminants
  • Helps increase gas mileage
  • Improves engine performance

  • Q:

    I forgot which direction the old filter was facing and now that I have my new Advance Auto Parts fuel filter I was wondering if you could tell me which end goes where? I noticed two small arrows on the smaller end poniting towards the end that has sort of like a cap on it. Is that the direction of gas flow? Any help would be appreciated....thanks.
