Fuel Filter Related Repair Advice

  • Many manufacturers don't specify a replacement interval, but it's wise to replace the fuel filter every 30,000 miles
  • We recommend using high-quality fuel filters to keep contaminants out of the fuel system
  • Infrequent fuel filter changes can lead to potentially expensive problems with the fuel pump and/or injectors
  • When replacing a fuel filter, the shop should also replace any associated washers or seals to prevent leaks in the fuel system
