I convert my Model A pumps to use a carbon seal and sealed ball bearing in the front. No leaks yet. I have made a couple of castings with slight modifications (none that would be visible) so that I can put a modern ceramic seal in. I figure that should last for the next 90 years (well, almost). When I get time, I will machine them and get them going.
