You've got three choices here to stay away from the purchase of a new tank--which I guarantee you will reel you when you see what they want for them !! It ain't pretty !!!

First of all-- alot of this is going to depend on the size of the hole in the tank--- if it is relatively small to medium sized you'll be able to do these two "patch" functions quite easily in fact --- if the hole is much larger--- you may have to go immediately to option three and forget about the "patch" options all together !!

You may want to do a temporary patch---and I stress Temporary here--- this will require you to have the place clearly marked where the hole is-- AND then-- completely draining the tank of gas --- it is imperative that the tank be empty while doing this--- next you will need a product by the name of----- J B Wield Quik ---- it is a two part chemical cement that once mixed sets extremely quick and double double tough ! So, once the two parts are mixed---you will have to work extemely rapid !! use something like a popcicle stick to mix the two parts and to apply the mixture to the hole in question--- taking pains to spread the mixture evenly and completely over the hole and smoothing the substance out for some distance around and larger than the hole being filled--- in something like 30 minutes you should be able to replace the gas in the tank and resume your travels---- but remember that this is a simple temporary fix and it is suggested that you move to one of the next two optiions for a more permanent solution as rapidly as is possible !!!!

Second option here is to take the car to a repair center and have the hole professionally repaired---- a lot of places that do radiator repairs can do this repair on fuel tanks because they have the equipment and the know how to do this and are considerably less expensive than regular "body shops" that in a lot of cases would simply take this item to the place I'm telling you to go---and charge you extra for having done so !!!
These places will remove the tank completely and drain it---then they steam it and vent it to completely remove ALL gas residue --- even the residual fumes--- then they actually wield or "braze" the hole to form a permanent seal--- this in the long run will be your best option in the repair "thing"--- you can expect to pay somewhere around $ 100 to $ 125 usd for this service !!!

Third and final option--- find a replacement tank on a car at any "junk" or "salvage" yard you can find and pay someone to take both tanks off and replace your's with the salvage yard purchase !!!

I hope this helps in some way and gets you guys back on the road !!

Depending on what caused the hole, if it was rust or corrosion I would recommend replacing the tank. If something punctured the tank you can patch it with a product called JB Weld it is available at most auto parts stores. Just make sure the fuel is not leaking while you are putting on the patch or it will not stick. If it is a plastic tank there is no safe fix, it should be replaced.The value of replacing the tank depends on the make and model of the car. Check around at salvage yards. If you can afford it I would replace the tank for safeties sake.

Answer 3

Places are really shy about welding on gas tanks. You may be able to find a radiator repair shop who will boil out the tank and weld the hole. If not, try a salvage yard, but inspect the tank well. You don't want ot buy a tank with a hole in it. If all else fails you can get a new one from a dealer. He will have to order it, more than likely.

Answer 4

The safest way is to drain and remove tank and take to a radiator or simular repair shop,look in yellow pages and call for price.To temporarily fix if hole not big or on seam you could put a screw in it with a sealer like J B weld.also you can drain,let dry and put a metal patch on using J B weld.
But be careful not only gas but fumes are explosive.
Best be safe and have repaired by a professional.

Answer 5

it depends on what kind of tank. Most newer cars have plastic, then you're best off replacing it. Gas tanks aren't very expensive it probably worth just replacing it than draining and removing it and patching it. It depends on how much time you have on your hands. And welding a metal tank can be dangerous if you're not very smart.
