go to the harbor freight store and get a dc powered fuel pump or a pump that goes onto a pistol grip drill and a short length of garden hose with fittings. get a five foot length of pvc pipe. put the pump together with the hose and pvc and pump out your tank into a 55 gallon drum. the drum only holds 55 gallons, so if you have more fuel, use more drums. Ideally your tank base should include provisions to contain any spillage, a curb, so to speak of if fittings leak or the tank itself leaks. when you place the tank, elevate the "out" end slightly above horizontal so that condensate water drains into the other end and it doesn't freeze in the outlet pipe or tubing going to the heater.
