Purchased this to replace the failing pump head on my Lifeline track pump - with a little bit of modification, in terms of shaving a bit of the pump hose, and drilling-out the screw hose connector, that secures the hose to the head, a perfect fit was achieved!

The Leyzene pump head has effectively breathed life into my old track pump, which still has plenty of miles left in it, before I'll eventually have to replace it. Had lifeline offered spare parts, then I would've used them, but they don't, hence the Leyzene purchase.

So, with a bit of mods, all's good in the hood with this quality Leyzene part!
