The " Pond Snorkel" derives its hydraulic power from the Auxiliary hydraulic system, A 10 inch diameter flexible "tube" is attached to a 90 deg fitting at the front left of the tank. A 19ft long 3/8 inch cable runs inside the snorkel to carry the weight of the snorkel head. Also running inside the tube are 3 hydraulic lines providing fluid flow to the Hydraulic motor driving a brass prop in the snorkel head. This hydraulically driven prop is what actually pushes the water through the snorkel into the tank during filling.
