Zefal used to make a full-sized frame pump (Zefal Soliblock) that had a screw-in hose, so the body of the pump wasn't attached directly to the tube's valve.



The Zefal HPX is still being made. Rivendell sells it and you can probably get it off Amazon as well. Might be possible for someone to come up with a short hose adapter to put on a current frame pump. Perhaps modified from a floor pump replacement hose.
