I am sorry to find Gentlemen but have stuck this OEM dirty rubber nipple in my gob and truly vacuum sucked as hard as a bong smoking pot fiend could possibly do to no avail trying to close this suckers lips up safely for crud sucking potential
Unfortunately too Daz the rising inner tube wicked solution will struggle to work I believe for this specific airboxes position/scenario found as there is zero swing/elevation room for the tail end to complete its cutoff mission under swamping.
Have started plumbing up a fully sealed system with an old school manual drain that should sump/pipe snorkel splash collect up to a calculated 0.5L before the external lowest release valve to come needs releasing
Have tried to replicate the rubber OEM nipples sump (floor level) slots as best as possible and truly appears now the last dregs drains faster out too as it has 50% more holes (4 slots versus 6 hexagonal holes)
