Easy way to pump gas out of gas tank

[Old Redneck]

I got two cars that I half to pump all the gas out so I can wash out the tanks. One is the 56 Tee Bird and the other is a 63 Split Window Corvette. Here what I did I went to Tractor Supply and bought a Battery pump that takes two flash light battery. Works super in a few minutes the gas tank was dry. So if you ever have this problem that the way to go. Yesterday I ordered a heater motor for the Tee Bird and it came today. I ordered the parts from Hill's in southern Ohio
