In order to do its work properly your fuel filter needs regular changing to fulfill its job in capturing unwanted particles and water circulating in your fuel. As a result, the injection system and nozzles will experience undue wear, and your vehicle or machine’s performance will suffer

If you’re unsure of potential fuel filter problem symptoms, here are some signs it’s time to get a fuel filter replacement:

  • Complete failure to start
  • Poor acceleration or a decrease in power
  • Sputtering or stalling at low speeds
  • Fuel efficiency is noticeably worse
  • System warning light comes on, indicating there’s a problem
