TECHNICAL MANUAL
FUEL TANK SWEEPING WITH FILTRATION
Overview:
The suction hose (green) is connected to the pick-up wand
(60” white wand) . The pressure hose (red) is connected to
the dispensing wand (20” white wand) . The fuel is filtered
as it is drawn from the tank and returned to the same tank
(or auxiliary tank) . By moving the wand along the sides
and bottom of the tank, water and contaminants that have
settled in the tank are removed . The sight tube aids in
determining the length of time needed to clean the tank .
Use the regulator setting of 80 PSI.
