If the good Doctor or some machinist can tell me how to dimension the part best, I can make those changes. Also it needs a little more detail on the chamfer, I just guessed from the image. So what is the distance that the chamfer starts, and what is the dimension of the narrow edge, is it about 0.010?
Now there is the problem that a modern hose is bigger in diameter, we need a 63529-17 that will work with an available oil-gas hose I can get at the auto parts store. My old hose from the -57 tank measures 0.530 OD. The auto parts hose measures 0.550 but it is a little elliptical, so that is a guess. That would only leave a 0.010 ring, pretty thin.
Also the used rings in the picture below measure 0.650 at the big diameter, so that is more than the OP says.
Here is the picture of the hose that came on a -57 tank I got on eBay years ago:

I am also showing a nut that came on another tank, but is sure not the same nut on the hose, despite screwing onto the same fitting. Here is a close-up. Anyone know what that smaller trimmer nut is for?

I suspect a 1/8th inch strip of heat shrink around the hose and the nut would squish that enough to retain the hose. Its not like it holds any pressure and the way it sits, there is really no force to tear it off.
