Related Repair Advice

  • Since Diesel fuel attracts water naturally, a diesel fuel filter can be equipped with a water separator and drain so that any water that might build up in the fuel system (between fuel filter replacement intervals) can be removed
  • 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
