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)
