fuel tank plumbing

So far, I am down to two concepts:

1) feed header tank from either main fuselage tank or upper wing tank with a
main/aux selector valve

2) feed header tank from only the main fuselage tank; fill main fuselage
tank (only until sight gauge shows full) from the upper wing tank via a
shutoff valve

Any other suggestions? (keep 'em simple)

The simplest is to plumb the wing tank through the aux side of the
fuel selector valve directly to the gascolator and use a vented cap.
You haven't really given enough detail about how your main and header
tanks are set up and connected. Will you have a fuel pump or is
everything gravity feed?

Everything gravity feed is the objective. The header tank sits on the =
cockpit floorboard, directly underneath the main fuselage tank. The =
12gal main tank is plumbed directly with fittings to the aft end of this =
cylindrical header and the gascolator is mounted on the foreward end of =
it on the engine side of the firewall. The main tank has a vented filler =
cap, as does the upper wing tank. Presently, I can find no shutoff =
valves installed, but plan to install one when I figure this out.

Thanks,
