I am getting ready to seal up the fuel tank in the upper wing center section and a couple questions come to mind.I purchased the upper wing tank from Steen Aero Labs. Is it necessary to "slosh" and or pressure test this tank? And how are the openings in the upper and lower plywood skins (filler cap, feed line and vent) sealed up. I have got maybe 1/8" or so gap around these openings. Grommets? silicone ? fabric? Nothing at all?
