Plastic gas cans are used as back-up fuel containers for vehicles, or to fill up lawn mowers and other gas-powered machines. Unfortunately, the plastic can crack from long-term exposure to the elements or be punctured by sharp objects, causing the gasoline to leak. Fixing your plastic gas can will prevent you from having to buy a new one.

Step 1

Dump out any gasoline in the gas can.

Step 2

Locate the hole or crack in the gas can. Determine the size of the damaged area.

Step 3

Cut your plastic into a size that is large enough to patch the crack or hole.

Step 4

Place the piece of plastic on a large metal or other non-combustible surface.

Step 5

Heat the plastic piece with the heat gun until it is pliable and transparent. Heat the area of the gas can that is damaged as well.

Apply the plastic piece onto the damaged area using tweezers. Connect and smooth down the area with the hot knife.
