Default Re: Putting a drain plug in a gas tank?

When we had to weld a steel gas tank back in my snowmobiling days, we'd empty it as much as we could and then took the hose from my mom's vacuum cleaner, shove one end up a car's exhaust pipe and put the other end in the tank. We'd go into the house and have a beer. Then we'd come out and weld away.

Just make sure the car you use isn't running rich.
