Just passed my final inspections on the addition I built onto the house and the inspector was checking out the car and asked if it's normal for the fuel tank to be dripping like that. I looked under and sure enough it was dripping a drop every second from dead center on the bottom. I sprayed a bit of brake clean at the area to remove the under coating in about a 4" circle around the drip and found two pin holes streaming fuel. The metal looks perfect around the pin holes. The metal looks brand new and has NO grinding marks. (like it bottomed out). I've been driving the car 3-4 times a week for the last couple of years so it seems unlikely that water would have settled on the bottom and rusted it out from the inside.
What do you guys think?
In the mean time I have made a couple of rubber washers out of fuel hose and used a couple of sheet metal screws and threaded one into each pin hole. The leak has stopped. Do you think its time for a new tank or this fix could be permenate?

Time for a new tank. I've found that the appearance of the outside of a fuel tank can have little bearing on the inside of the fuel tank. It's likely a lot more rotten thank you think. rockauto.com

I've had the same happen a number of times. There are now repo tanks for many models that are reasonably priced; I've had very poor luck with junkyard tanks (generally, they're no better that what I was replacing). I've tried various "fixes" including a liquid white-latex-paint-like sealer and (polyester) fiberglassing the whole tank. Both of those techniques worked for a while, but a new tank is a whole lot better.

I have heard of outfits dipping your old tank into molten polyethelene and coating it that way as a permanent fix, but I've never tried it. I have a poly tank in my truck that seems to work fine.

in every case where ive investigated "gas tank renU" as an option for fuel tank repair, the price for the job was within $5 of the cost of a new tank.

it would be AWESOME if some enterprising company began making polyethylene tanks as direct-fit replacements on popular older vehicles.
