Thanks Bobby.
I assume the RV-10 have dihedral wings like the RV-3, 4, 7, 8 ... ?
What I'm trying to understand is, with full tanks, how does fuel not get siphoned out the tank via the vent line (without the loop well up above the top of the tip of the tank inside the cockpit)?
With full tanks and then fuel expanding on a hot day.
Why would a loop like they use on the Rocket, be any better than the straight down on the RV-10?
(Oh, the RV-10 is nose wheel only? no tail-down attitude on ground -- so there will only be one high point in the tank except during climb-out where the is dynamic pressure into the outside vent line?)

Finn,
For the RV10 the vent line is installed through the bottom wing root fairing. Bobby

This looks very tempting.

But can anyone explain the physics of it?
RV vent lines run from the upper tip of the tanks (next to filler hole) and then normally into cockpit, up cockpit wall, loops down to floor and into 90 degree fitting down through floor and pointing forward.

There is a mention of RV-10 vent lines, that gives the idea they just come out of the tanks and down and out, but no pictures.

(Still figuring on where to put vent, transfer and return fittings in right tank)
