Looking for coments, and figured this was the right
group to get them.
My plan is to copy Tracy's fuel system with one
tank feeding the other, and the second tank feeding the engine with a return
line. But today I looked at one of the drawings Vans sent me (DWG 31A
for the RV-8). It is for the RV-8A, so I had ignored it before. It
shows the return line from the engine (or pump) connecting back to the feed line
just after the tank selector valve. This seems to me like an easier
answer. I wouldn't have to add a second pump to move fuel between tanks, and the
return line would only have to go to the valve, instead of all the way to the
wing.
Will this work? Or am I missing some obvious
cavitation/starvation problem?
I've attached the part of the drawing that shows it
best. Instead of running the return from the pump, it would return from
the fuel rail.
Thanks in advance.

P.S. I pick up my mount from Fred next
Thursday. So I should soon be building my cooling system and plenum.
I'll post pictures as that develops.
