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  :>)
