Fuel venting danger

>>What better place than the fuel cap itself ? (You could then dispense with a
piped vent altogether).<<

That sounds interesting, let me ( and you others) think about it. You do need a
separate vent when filling from a bowser because the filler pipe will fill
completely at moderately high filling rates. You are right about the unfilled
airspace when the plane is tail down. It is a nuisance when you are planning a
long leg across France.
