Am I missing something obvious here ? Or is it that a non-return valve is counter productive on a tank breather and pointless on an overflow?
The tank has to breathe out when sitting in the Sun or anywhere else warmer than where it has just been.. And in when the level goes down in use. It's a two way flow.
The valve must allow fuel outwards on an overflow, but what exactly is it preventing from returning if the hose is routed far enough downwards?
Sweet little valve though... There must be somewhere you can use it.
