Same old principle, keep it simple.. Don Skeele
Angier,
Keep it even simpler. As designed, the header feeds the engine pump and, if injected, an inline "boost" pump. Ergo, the only requirement is to keep the header full - thus resulting in 1 hour of flight after a variety of failures (losing fuel via cap or leak, total electrical failure, etc). Every other complex design with valves, check valves, crossovers, interconnections etc. only exist because of a mind set to continue to the destination after some failure when, for safety's sake, plan B should be utilized (land now and fix the problem).
KISS = keep the header tank full.

Re: Don's concern about siphoning from the header tank filler tubes, I did install check valves at the header tank in those tubes.
