    Ask your local fire department. When my truck picked up a gash in the tank from some freeway debris, I couldn't avoid, I donated my old plastic tank to the local FD so they could practice their patching skills on plastic tanks. They had patches on my tank's gash, but with fuel seeping out............it took numerous trys to stop the leak.

    This may not be much help but...
    Back in the mid 70's, right after a fill-up, I got a fuel tank leak on the bottom of the metal fuel tank , on my 1969 Chevy Van.
    Gasoline was dripping all over the ground and the whole bottom of the tank was wet with gasoline.
    Right next door to the gas station was a automobile radiator repair shop.
    A guy from the radiator repair shop, brought out a tube of "Aluminum Repair".
    (It's like a paste inside a tube like toothpaste comes in, only the tube was a little bigger "Aluminum Repair" was the name on the tube)
    The guy claimed they used this "Aluminum Repair" for repairing some leaks in Radiators, and had great success.
    He smeared a gob of this "Aluminum Repair" on the wet leaking area at the bottom of the tank.
    The leak stopped instantly, and never leaked again for the 3 additional years that I owned the van.
    I'm not sure if this "Aluminum Repair" is still available, but I think a product like "JB Weld" would give similar results, if you have a metal gas tank.

    IF the tank is metal, take a bar of Sunlight soap and scrub it on the crack crossways. lengthwise and diagonally. That should stop the leak. Other way is to take tank off and steam clean it and either weld or solder it up.
    (I am not affiliated with Sunlight Soap and will see no profit from this remedy.)

    Is it metal or plastic? I've had good luck with the stuff they sell at the auto stores to patch metal tanks, but nothing has ever worked for very long on plastic tanks. In the end, and after a lot of frustration, I always have to replace the plastic tank. If I can, I try to find a metal one because whatever happened to the plastic tank that caused it to leak, happens again with the new replacement plastic tank.

    I repaired the plastic tank on my LS in 2010 and it is still holding. I used JBWeld two part epoxy mix, roughened up the area with a power brush, cleaned it thoroughly with acetone and applied the JBWeld. I did have to remove the tank as all the holes (4) were on the bottom. I still have the new tank that was furnished under warranty setting in my shop just waiting for the repair to leak. So far no issues. You do need to severely roughen up the area to give the epoxy some gripping area AND clean the fuel off good with acetone or naphtha.

    Give me a plastic tank any day of the week.
    The seams never start leaking, they don't rust from the inside out, much easier to repair if a bit of bad luck happens.

    Do we know if the op has a plastic or metal tank yet?

    I ordered a can of fuel tank repair for my WD45 from JCWhitney. You just take the tank off and roll it all around. This also seals all rust. This stuff looks like contact glue used on formica. (this was in the eighties dont know if they still make it). My repair is still holding.
