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!

  • Defense against damaging contaminants
  • Helps increase gas mileage

    Comments about Purolator Fuel Filter:

    This is a great price for this filter at Advance Auto. I use this filter on my Ferris commercial mower. It had a smaller filter on it and started to run short periods at a time then it would quit. After searching the internet someone suggested changing to a bigger filter. I had ordered the same filter that came on the machine and it still would stop after a few minutes. I thought what a stupid suggestion but I had checked and tried everything else. I put the filter on and it has never stopped on me again. Weird solution since it had worked on the original smaller filter from day one. Anyway, its working now and thats all that matters. I also use it on my sandrail and the filter has never failed me.
