another use for an extra behind the seat gas tank.

[zyggy72]

I got tired of running about 2 hours into town several days a week to dump my used oil.
Solution: I took an extra behind-the-seat gas tank, washed it out, cut 2 small holes in the bottom on either end, cut the sending unit out and then I welded the fittings from 2 55 gallon drums to the gas tank. The two smaller fittings were welded to the bottom, one of the large fittings was welded on where the sending unit was and the last large fitting was welded to the gas tank filler neck.
Now I have a used oil tank that seals and is easily emptied that can bolt into the back of my truck.

Anybody have any similar ideas?
