Question about Jeep Grand Cherokee
I don't think you will have any luck sealing this from the outside.
Removing the tank (preferably empty), filling it with water and soldering all of the seams (if metal) or replacing it if of plastic.
This could be sloppy manufacturing showing up late, stress from being slammed underneath (is there signs of dents or scrapes?) or if metal, it might be rusting through which is pretty much a death sentence for it.
Pouring some (a cup or so) methanol, pure ethanol or a commercial product intended for that use, into your tank now and then will cause condensation to bond to the gasoline where it will pass though the system and out.
