I've been studying all the stuff about fuel systems on the Matronics forum. There seems to be a consensus that you need a header tank, usually installed behind the seats somehow. But there doesn't seem to be any mention of why.
Anybody know why we need a header tank?
Is it so you can draw from both tanks? I'd just as soon not do that. I like redundancy. Or is it because the wings aren't high enough to provide enough fuel pressure when you're climbing or something?
I'm thinking of just running both fuel lines to a Van's-style fuel valve, with an electric fuel pump ahead of it just like on my RV. Anybody know why that would be a bad idea?
