engine out of a diecast car and random gas can with a lot of scrap plastic

I had this engine out of a trashed diecast PT Cruiser. It dawned on me that it would work well to make a generator. I built a frame out of plastic tubes, I mounted the engine in the frame but it was incomplete since the engine was out of a car it did not have a built on gas tank like a generator would. I debated for a while about how to resolve the problem and finally settled on using a fuel can mounted on its side.
