The misson is to repair the manifold so a air valve can be installed to be able to fill the tank.

The casting on the tank broke off eliminating the air valve

purchased a air valve for a couple bucks, determined the thread count to be 18

Drilled hole per tap instructions (7/16) Although this thread od is almost 1/2 inch it’s called 1/4 pipe thread. I’ll
provide the tap chart for referance

Adding a air guage would just top off this great repair. Not! Tightening the air valve the mainfold again fell apart. At this point the manifold is deemed unreliable and tossed in the recycle bin

Back to the Basics. All I really wanted to do is not have to haul out my compressor to air a distant tire
