seems to me that the "hose" = "adapter"??
the madison pontoon boat made by classic accessories years ago was equipped with the "boston valve" and was also supplied with a short length of clear tubing "adapter" to properly use the double action hand pump shown in the first post.
the odc super sport by the creek company also was equipped with the same valve and clear tubing "adapter"
i currently have outcast super fat cat float tube that is equipped with the summit 2 valve and the "adapter" similar to the one shown in my previous post.
as long as i dont lose the "adapter" that came with my float tube :lol: i wont have to go crazy trying to find a 3-4 inch long of god only knows what diameter of garden hose to use as an "adapter" ;):D
