Just have a friend of yours help you if you cannot get the gas out. Me and one other guy got two Mustang tanks and a Grand Prix tank out with 3/4 to a full tank of gas. Once we got it down, we then emptied it into about three 5 gallon buckets. We put it back up empty, then fill it wit ha funnel. We only spilled a gallon maybe when the Mustang tanks shifted on us.
