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.
