A clever, 2 ball valve system that
allows air into the tank to replace used fuel and allows air out due to expansion
but will close off to prevent fuel escaping in the event of severe sloshing or a roll-over.
Fits through an 11mm hole in the tank.
Access from inside the tank is required to fit and
tighten the nut.
Maximum height above the tank 11mm.
7/16” UNF (JIC 6) thread with a nut and an ‘O’ ring.
Overall length 29mm.
