Fuel tank pin hole
Symptoms. When take us filled, small weep fills sender well with a small amount of fuel, and stops. No gas hits the ground or even the sides of the tank. Even still full, will not leak no matter how long she sits after the first fill. Drop the tank down a little and found the small pin hole. Possible screw from PO? No idea.
I have a spare tank, but the kiddo decided it needed to be filled with mulch.... Ugh.
I want to fix this micro hole. I am thinking epoxy.
Thoughts guys?

Surely you have something small enough to fit in there to plug it

Look up "Welding Polypropylene". Temperature should be around 570F. I scraped a sliver of plastic off of the mounting bracket at the top of the tank gooseneck and used it as a filler. I used a carpet seamer iron to melt it on the crack I had.

Aside from welding, I know of no epoxy that can be used to seal plastic. I went through quite a bit of research on this with an old Land Cruiser with a leaky aftermarket plastic fuel tank. Ended up replacing it with a stainless one.
There are a "few" plastic formulations that can be epoxied but to my knowledge gas tanks are made of this. Either find someone to weld it, or replace it. I saw somewhere that there is a plastic welding kit which uses heated staples but I don't remember who carries this. Someone may chime in who knows.

On my land cruiser someone before me had tried to use fiberglass... it did not hold long term.

I used a small small chunk incur off the spare tank (edge/flashing) and used a hot spoon handle to melt it in to the hole..... Was real easy. I also replaced the "camper topper" foam seal I used last time on the tank spider. I used this stuff from Home Depot . Works fantastic.
After the kid gets up from her nap, I'll head out and fill up an see what she does....

Leo over on pelican used plastic weld rods and a plastic welder from harbor freight. The rods are not very expensive, and I found them at Grainger.
I used plastic weld on my crack a few months ago....so far so good....it's a 2 part epoxy....crack was down low on the hub for my internal fuel strainer.

A since-soived small fuel leak that I had w/the GT made me gaze appreciatively at the little Halon fire extinguisher that I have mounted next to my driver's seat. Not a preach, just an anecdote

The PO of my 84 put an awesome stereo in the back--3 amps, subwoofer, CD changer, etc. He used sheet metal screws and had a 100% success rate at screwing them into the top of the gas tank. Your PO may have done similar.
I dropped the tank and used a plastic gas tank repair kit from Pep Boys or Advanced Auto and it worked very well. At least on the top of the tank--no idea how it would hold up under the fuel line level. I think I read that some have used JB weld(?)
Here's a pic of Johnny Torch's stereo:
