Abstract
An apparatus for withdrawing the fuel form the fuel tank of a liquid fuel powered vehicle and discharging the fuel into bulk storage tanks includes a pump that is selectively actuatable for pumping liquid fuel and having an inlet that is connected with a hose having a portion of sufficient length and flexibility to be inserted into the fuel tank of a vehicle. The hose is adapted to extend through the vehicle's filler pipe to the bottom of the tank. The pump has a liquid discharge conduit for connection to a fuel storage tank. A fuel meter is provided that is adapted to measuring the quantity of liquid being discharged by the pump into the discharge conduit. The hose may include a shutoff valve, which may be an automatic shutoff valve of the type used at gasoline stations.
