    A friend of mine has a Chevy Malibu 2001, he bumped the rear on something and now the tank is leaking from a small crack. A new tank is 616.00, does anybody know if the tank can be fixed. The tank is made of some kind of plastic material.

    Dry the tank and use an epoxy made to be exposed to fuel.

    they make a small electric thing called a plasic welder, that will bond plastic together, ive used it on many things that hold gas,water,and many othere things, check it out, they should be able to get you one at any hardware store.

    You can rub a bar of soap into the crack to stop the gas leak temporarily. Then just clean the area and use some epoxy to fill the area if it is small. If it is big, you should probably pull the tank and do some sort of plastic weld.

    marine tex, it will fix anything. it is made to repair cracked blocks, maifolds, and heads. i put it on my toyota a while ago and it is holding up better than the rest of the tank.

    Boat stores and occasionally gun shops as some use it to bed rifles. The plastic welder would be the more permanent cure. Harbor Freight sells them too.
