Well; there is, but of course it is
dependant on air frame design. My Velocity has gravity feed from both mains to a 3 gallon sump,
gravity feed from sump to the EFI pump; regulator return to the sump. Now
that's simple.

It obviously works for you but I still have a hard
time thinking about how the sump tank vents properly. Maybe it
doesn't need one? Or do you vent it up to the mains. But then
there's that complexity again :>)
Tracy (just trying to wrap my head around this
system)
Well; OK. I didn’t mention the
vents – but that’s simple as well. A vent line from the top
of each main comes into the cabin at the firewall (back near the firewall the
side of the cabin is the inboard wall of the main tanks); and the vent from the
top of the sump (which is at the firewall) comes up to where they manifold together
near the top of the firewall (above all fuel levels). From there a single
line comes off the top of the manifold, makes a U-turn and exits out the bottom.

P.S. Tracy; did you get my e-mail
re the TC alarming; or is it just as much a mystery to you?
