Advice, please. The Joe Blow track pump is waiting for me to fit new seals, the Lezyne miniature track pump is just brilliant (and Highly Recommended), the little electrical pump from the Jazz works but is slow and isn't always at home, and the previously trusty Michelin double barrel foot pump is U/S. But at least I now know why: I can get a replacement hose but what can I do with that fitting? The white metal crimped end swivels freely on the yellow metal piece. And a whole new pump only costs £18. Thanks Jonathan
