Any way to patch this hole??

Mechanic applied some kind of "goop" (not sure what it was) but it didn't last that long. Must be some product out there that I could use to patch this hole and avoid having to buy a new tank?

Mice had quite nest there when it sat for some time last winter but for the life of me I can't imagine that there weren't a lot of better tasting things to chew on than my gas tank!

Maybe try some "Hot Melt Glue".

That can be welded with a plastic welder, unfortunately the good ones are rather expensive. Maybe rough it up with a rotary rasp in a drill or die grinder and try some two part epoxy. If the holes are big enough that it would run through into the tank, and you can't reach it from the inside to put some backup tape in, maybe some of that epoxy putty?
I'd opt for the weld if at all possible. Perhaps ask around at some of the places that work on mowers and things with plastic tanks, they might be able to tell you who does that type of repair. If you had the tank off and prepped it would only take a few minutes to fix.

I agree, use a plastic welder. I bought one for about $150 and it was worth every penny. Be sure there are no fumes in the paint in the tank.

Doesn't look that big.

I'd try the gasket sealers first, if by chance that don't work take it by a radiator shop and they can repair it. They weld plastic radiators all the time and could weld your tank also.

Seal all made for gas tanks.

I repaired a tank similar to this using a soldering iron to melt the area and filling with a melted plastic zip tie.

A number of great suggestions! Thanks to all for the input. Given it's a pretty small hole I'll probably start with some of the most inexpensive recommendations as to materials that can be used and see how that works out. I'll post back the results-- good or bad.
