manual calls for 1/4" vent line; there is a FB 3/8" line with AN fittings in wing. Justin at Lancair says to make it 3/8" and use hose clamps....his normal quick answer. 3/8" looks too big for the NACA scoop opening. Probably going to go from 3/8 to 1/4 using automotive fuel hose and use a 1/4" tube into NACA duct
