The Wallas #367215 adapts any Wallas diesel product to a Wallas plastic tank.  The assembly is 4 meters (13′) long and includes a bronze fuel filter on the end.  To shorten the assembly, simply remove the filter by unscrewing it from the nut, sliding the nut assembly up the tube and cutting the tube.  Reassemble the filter to the nut and the job is completed by making sure the filter lays on the tank bottom.
