If I buy the Andair fuel valve from Vans for my 10, will it work with an extension I buy from Spruce (or Andair directly)? It would seem (I think) that Van's doesn't sell the extensions, and Spruce (I think) doesn't sell the valve model best for the 10. And I don't know for sure if there is something special about the valves with extenders - in other words, I'm not sure if a standard valve can be used with the extender. I'll buy direct from Andair if necessary but I'm guessing with exchange rates and overseas shipping I might do better through Van's and Spruce.
