Vent Lines



I just purchased N200PJ SN2 G200. Awesome airplane I look forward to really getting to know it.

On the first leg of my trip home, I got a fuel leak from a vent line. The vent line that was leaking was a vinyl or Tygon line from the bottom of the tank tee'd in with the drain that went up the tank and tee'd in with the normal vent. See the picture vent lines are in yellow. I'm of the opinion that this line isn’t needed since the regular vent should still allow venting in inverted flight. If it is needed it needed to be an aviation fuel line not a Tygon line. Anyone got any thoughts on this?

With this setup this line getting brittle and breaking could drain all your fuel. Lucky for me it broke half way up and only drained the top half.
