If you are lucky the only thing that need to be changed are the O-rings in the valve. They are quite easy to change. But you must be careful not to damage the "locking device" that secures the airline.

I think that you can use an O-ring with innerdiameter of 4,76mm and the thickness 1,78 (or it might be 4,8mm*1,5mm).
