I believe at least tri-gear builders should consider local climate and intended
runways, as any snow, ice, mud, or goose crap* can block a vent. With one fuel
tank, fuel flow will cease, and hence FAA rule about one tank, two vents.
FAR 23.951 and ff don't apply to homebuilts, but sometimes FAA "ain't just
whistlin'
Dixie."
I thus have a second vent, OK on the bottom if one is elsewhere. It's fed to a
mechanical fuel sender flange on top of the tank.
*The Canadian geese problem is so bad here that the airport manager leaves the
snow blade on the truck year-round, to plow the runways!
