the package instructs you to drain the fuel filter reservoir
Expert:  Gary replied 6 years ago.
this is how you change it.there is no drain to let the fuel out of the reservoir.just follow this and you will be fine

  1. Fuel tank filler cap.
  2. Open air bleed valve on top of the fuel manager/filter to release any pressure in the fuel supply system.
  3. Element nut by turning it in a counterclockwise direction. If unable to turn by hand, a strap wrench may be used to "break loose" the element nut.
  4. Element by lifting it straight up and out of the header assembly. It is not necessary to drain fuel from the header assembly to change the filter element since the fuel will remain in the header assembly's cavity. NOTE : Make sure the mating surface between the element assembly and the header assembly is clean before installation.


  1. New element assembly by aligning the widest key slot located under the element assembly cap with the widest key in the header assembly.
    • Push the element in a downwards direction until the mating surfaces make contact.
  1. Element nut. Tighten
    • Element nut securely by hand.
  1. Bleed air from fuel manager/filter.
  2. Reinstall fuel tank filler cap.
