i agree with the sheet metal screw if that would work for you application and then some quick steel gas tank epoxy around it. they make regular repair kits but theyve never worked well for me. you could pull one from a junk yard to
 
I don't think JB weld would hold. A screw would "bit" into the metal. Then maybe some rubber undercoating?

I bet the dealer want to put a new tank in due to liability. If they fixed the leak and 10 years later if it leaks and starts a fire they will be held responsible in court. I know the average person wouldn't sue, but at least here in the sue capitol of the world, you can't be sure.
 
Gas is nothing to fool with. Go for the new tank from one of the previous post, and if you are not up to doing it yourself, schedule a local mechanic to do it, and also run it so the tank is very low before taking it in.

You might ask the mechanic if they would want you to have 5 gallons of gas in one or two plastic gas cans so they can put that gas in to make it usable after the new tank is put in.
 
PS: The new spouts on plastic gas jugs now days is realy unusable, be sure to include a long thin plastic funnel for putting the gas in the new tank.

Be sure to have at least 5 gallons. Some tanks take more than 2.5 gallons just to get them to begin being usable if they are totaly dry.
 
Lots of good advice above!

For a home job, the area has to be perfectly clean and dry.

No rust or gas at all!

JB quick weld with a metal patch of 3"or so diameter is what I'd do. Then spread more on top and go out further.

But REALLY clean and dry first! You may be able to jam a little JB in there to stop the leak, then clean the outside area and patch it.
 
Use the JB putty, easier to work with, preferably the water weld stuff. Use some wire screen if the hole is bigger than 1/8 inch.

Nine years & counting on the tank in my Caddy!

That works, use a piece of fuel proof material as a gasket. Plastic fuel line, whatever. What Ttoyota dealers do to the company reputation with their repair quotes is disgusting. The company lets them get away with it. Sooner or later it will cost them sales.

Whatever you do, don't forget how terribly dangerous gasoline is. Especially an empty tank full of fumes.

Singed eyebrows some 34 years ago was the one and only lesson I needed.
 
I agree with bdcardinal. The dealer wants to put in a new tank due to liability. We’re in USA. U can Sue Anybody. That is why they use an OEM tank. I price one online. Its $450 bucks. I tried to repair it last night using a cheap epoxy kit. It’s not a hole, more of a scratch. The kit did not work. It slowed it down to a drop a minute.
My luck on used parts is not good. I’m thinking of taking Texan4Life advice and ordering a new one from RockAuto. A new painted one is $122. The wife wants me to have our cheap mechanic put it in. She does not want me to blow up the car, the house and myself. It’s a major pain without a lift.
 
My driveway is on a slope. It slopes into the house. Bad design. My daughter’s car was park there and when I opened the garage door, the gas fumes ran downhill and filled the garage. You could smell it. Thank god it was windy.
 
If you get a new tank, it is a good choice. I only gave an option.
You can still repair it to buy time.
BTW, even if it is painted, consider painting it yourself.
 
My first year on the line I drew a 1990 Grand Marq for a fuel leak from the rear of the car. Customer was nice enough to fill it to the brim so the tech working on it could find the leak. Well. it leaked, so I got to pump it out by hand, oh fun.

I got it drained, everything disconnected, got a tall trans jack underneith it to keep the tank from dropping, pulled the straps out, tank no budge. Pulled/pried on it, no go, it was stuck hard.

Dropped the car and looked in the trunk and saw a bunch or radio equipment mounted under the package tray where the spare would normally sit. Kind of dawned on me what the problem was then. I proceeded to remove all of the mounting screws, 3" long self tapping screws, from the radios/amps. Soon as I pulled out the last screw, the tank clunked on the floor.

EDIT: As far as the dealership fixing a tank, it will not happen due to liability concerns. Got to wear a white shirt for awhile and those decisions aren't even close.

Gotta love it when the PDs drill into the trunk and then want the leaking gas tank replaced under warranty.

On a side note to anyone dropping a tank be very careful. Future Ford in Clovis, CA burned to the ground when there was a spark as a gas tank was being lowered on a F150 to replace a fuel pump. There is video of it on youtube, but after that we made sure to buy a stand alone gas tank lift and powertrain lift to CYA.
 
I dropped the gas tank on one of my 92 Cavaliers to replace the fuel pump and here is what I did. Jacked the car up and put my ramps under the back wheels and set the car back down. Put chocks under the front wheels.

Unhooked the filler tube, electrical wires and vent hoses. Siphoned out the rest of the gas using a hand pump through where I unhooked the filler tube at the tank.

I then put my floor jack under the tank and then unbolted the straps holding the tank in. I then lowered the tank down and pulled it out from under the car.

Installation was the reverse. Not hard at all. Siphoning the gas out took the longest. At $700, your mechanic is trying to screw you.
