My Zefal HPX (not a frame pump but whatevs) doesn't work. Clip it on to a valve and the handle shoots out as it fills with air from the pump so all you're ever doing is putting a one strokes worth of air into the tube. Valve failure somewhere? Same issue with several tubes so I don't think it's the tube.

What fix.
