The tank is finished!

I stopped at the hardware store and bought both oxygen cylinders they had. Ran them both out, too, though when the second ran out I was only reflowing some of the brazed joints for appearance’s sake.

It’s not my most beautiful brazing job, but I’m confident it won’t leak. Between the cylinders running out and me pausing to fetch fresh rods, etc, the bronze flowed a little wild in places, but it’s functional and will be covered in paint, anyway

I had to drill out the fuel pump mounting holes to account for slightly misaligned mounting bolts, but it didn’t take much to mount the pump. I even verified that it spins!

I wire brushed the filler spout, drilled out the mounting holes, cut a gasket and bolted it in place. In pressurizing the tank with a little air, the only leak I can detect is around the filler spout. It is cast from aluminum the sealing surface isn’t really flat. I worked it over with a file and it’s much better, but still leaks a little air. I will apply a little gasket sealant and that should take care of that.

I put a valve and a very short hose on the old fuel tank outlet and will use it as a drain.

All that’s left is to sand, paint and install it.
