Fuel tank tap and pinhole repair

The joint where the fuel tap joined the fuel tank was leaking and looked as though it had been repaired with epoxy. Before starting any work on the tank, I flushed it out with copious amounts of water and then placed it upside down overnight so it could drain.

It appeared that incorrect primer was used on the galvanized finish, as the paint was peeling off the galvanized tank. After I cleaned off the old paint, the best solution appeared to be to remove the seat for the tap fitting, plus the feed from the start tank (gas), and re-solder them.

The fuel tank has a small compartment to hold gas for starting, then it can be switched over to kerosene for running. The leaking fitting almost fell off, and the copper pipe from the start tank was sawn through to remove the tap. I melted the solder to remove the remains of the pipe from the gas tank.

First, I cleaned up the hole in the tank for the tap seat and then enlarged it until there was a ring of strong, clean metal before making a boss to fit in this hole. I turned this new boss from a piece of brass and tapped 0.50-inch NPT for the tap fitting before soldering it in place.

I soldered the copper pipe from the start tank to the two-way tap into both the tank and the tap. This meant that if the tap had to be removed for any reason, the solder had to be melted. To make such a task easier, I made a small compression fitting to screw on the end of the tap. I then soldered a new piece of copper pipe to the tank.
