Default Fuel Vent Line - Problem with the "SharkBite" Tee

In the fuel vent "T" connector behind the cargo bulkhead, the "T" branch for the siphon killing tube has come out of the connector. This connector is the "SharkBite" style which has teeth in it to grab the tubing. Has anyone, besides me, experienced any unreliable retention of the tubes that go into this connector? After this tube became disconnected, gasoline overflowed into the fuselage the next time I topped-off the tank. Also, has anyone experienced any leaks of gas fumes from this connector? Is there an alternative design available for this fuel vent system for the RV-12?

I have had the same issue. Had not noticed/smelled fumes in the cockpit.
But during annual last month I found the small plastic vent tube disconnected from the T-connector. Design seems rather flimsy in my opinion and I would have preferred a more robust connection for these lines. Was able to reconnect them, but I'm thinking an upgrade/change is in order. Interested in whether anyone has addressed this issue already.

Jim & Brent ... wondering if the root cause of your issue is that the aluminum line has pulled back into the baggage area enough to allow the quick release ring on the "T" to get compressed onto the baggage bulkhead enough to cause the releasing of the aluminum vent tubing?

Edit: Disregard ... I see you are talking about the leg of the "T" and not the inline connections ... I didn't read close enough.
