Thanks for the ideas fellas (Todd, Colin, Larry). First up I'm going to slip a short piece of tube square cut over the 45 chamfer on the vents to obtain a more static pressure and confirm the nature of the beast then options are either, fly on one tank only (ie. prevent cross flow thru the tap), one-way valves in the lines, or seal the vents up and use one way vented caps....if none of that works I'll go into the wing....failing that I'll fly upside down like all you people in the northern hemisphere with a wonky compass dip...couldn't resist :-)
