Fix a broken floor pump, replace pump head The little plastic lever to tighten the o-ring broke on my floor pump. It's probably fifteen years old. The model is a Pyramid Pro. The broken bit is highlighted in red.



There's nothing else wrong with it and it seems silly to toss the whole thing over so small a problem. Is it supposed to be easy to replace the head on cheapo pumps like this? I cannot easily figure out how any of the pieces are supposed to come apart. Neither end of the hose screws apart. There's a large allen key hole that I think allows for dismantling the whole lower plastic housing, but it's not obvious to me that the hose is in any sense replaceable.

I assume the answer is I'm just being stupid cheap and need to a buy a new pump. Just checking first.
Slica makes a very nice presta pump head (below), the cost in the US is around $35. For that it ought to work well – and it does. The connection is a Schrader (car tire) thread and it is a pain to find a hose barb with that thread. What I did was to cut off the end of the hose and then use the threads on the pump head as a hose barb. I put a hose clamp on it and it holds just fine.
