The gas tank on the Midget turnedd to swiss cheese a few years ago. Holes
popped up over the bottom (probably due to it being used on a lot of gravel
roads).
The repair I did consisted of Puttying the holes with solder. I used a large
soldering iron the type used by tinsmiths. It was necessary to protect the
bottom so I plugged all the assorted ports in the tank, added an air valve
and put about 15psi (or enough to expand the tank to simulate a load of fuel)
and did a 3 coat fiberglass resin layup over the entire tank. It added some
weight to the tank but it hasn't leaked (at least the present owner says) yet.
I felt the air was necessary to give the tank the proper shape when full of
gas.
