This inexpensive plug will aid the DYI'er in constructing their own fueling system, using a standard "Bitz" fuel Jug. The plug uses a DuBro #807 Cap fitting set (not included) and has an O-ring to help seal the lid.  The plug is designed to work with the last 3 generations of Blitz fuel cans, including the new "EnviroFlow" can.  The O-rings used will allow the use of Kero, Diesel, Gasoline, or Glow.
