Do you have all three pieces?
1)the plastic line (small) 1/8" dia???
2) it goes thru a small brass fitting that has threads on it
3) after that a small brass tapered fitting goes on the tip of the line and the very tip - it won't go past it. This is what I superglued onto the tip. So far it has worked.
4) then all I insert the line and (tip) into the valve line assemble and tighten #2 into it.
Before superglue just the plastic line would pop out and I would have to unscrew both brass fittings and start over.
