Hey folks been lurking for a bit, figured it was time to actually ask for some help. My combi valve-air pump hose broke when I was fudging around with my air pump..pos is made of plastic rather than rubber for some reason... so of course it got dry rotted and snapped off. Anyways, I got the end off the air pump, but the combi valve end seems to be stuck on there good. Any tips on how to remove that sucker? Obviously I tried to squeeze the connector, spin and pop it out like the other end, but no joy. It doesn't feel like it's melted to the metal part, in fact there is the slightest bit of play in it, but it just won't pop off for me.
