ABSTRACT:
This apparatus has a unitary, flexible hose assembly with an inner hose for discharging fuel or other liquid under pressure into a tank to agitate its contents and an outer hose for withdrawing the liquid and entrained impurities from the tank. A pump and filters on a wheeled cart are detachably connected to the opposite end of the hose assembly to continuously recirculate and clean the liquid without intermediate storage of the liquid before it is returned to the tank. The discharge end of the inner hose and a nozzle thereon project several inches beyond the inlet end of the outer hose. An adjustable valve introduces air into the recirculated liquid stream between the outer hose and the pump inlet to increase the turbulence effect inside the tank. For the same purpose the outer hose may be formed with one or more openings near its inlet end.
