Ordered some parts from Tuxing.com and they showed up in less than a week from China and delivered by FEDEX. Maybe they changed carriers but whatever they are doing I hope they keep it up.
Put it together today with the new parts, basically rebuilt the unit with new parts from the ground up. Tested it and it built pressure faster than when it was new. Guess I have a good back up for my Alkin now if I ever need it. Really pretty easy to rebuild. Had not done anything in my shop for quite a while. Felt good to work on something again.
