I went to the shop and had a short piece of tube lying around. It was 2.5" dia about 5" long so I slapped some ends on it taped in the speedfits and now I have the a soda can looking bubble counter. It works great much better than the aquamedic. I think the aquamedic wasn't sealing well at all. So much for trying to buy something to save me time. but all worked out.
