Propane tank overfill

[Oxonomy]

I'm in the United States but own an European version 1989 T3 Westfalia.  Recently when I filled the propane tank it apparently overfilled and began to leak propane through the overfill valve, the brass one with the press in plastic cup (the cup popped out.)  After a while it settled down and we camped over 2 months with everything working fine.


Back home now and wondering just what parts I need to order from Gunzl to fix it.  They list a "Codeux" safety valve, which sounds good, but also a "fueling unit with fuel stop", which also sounds like it might be what I want.

Have any of you faced a similar problem and what was your solution?  Thanks for your help.

Sounds like it just worked as it should ……. Mine has worked once when the fill point was at a too high pressure

As above. Not a lot to go wrong with the filler shut off float.
