Breather cap for Model 20

Recommended Posts

Hello all,

I am lucky to have a good friend that has a multi million dollar 3D printing machine at his work.

i supplied him the drawings from the USA Hupp club for the breather cap, he came up with this.
it was printed in Nickel - aluminum - bronze alloy, all I have to do is make the retaining clip.

That’s really cool, when you get them done I’d be interested in one.  I have an original on my car but like having backup parts.


I also recommend taking a 3/4 inch strip of scotch brite, and rolling it tightly so it fits snugly at top of breather pipe.  Still breaths, but will catch any oil that gets up that far...
