Header Tank

[paul.lennemann]

A couple of questions,

Do you run a fuel pump, either electric or mechanical, with the header
tank?

When the engine is off, I assume the fuel will equalize up the header
vent line to the level of the fuel in the wing tanks, unless you turn the
wing tanks off, am I thinking correctly?

When the engine is running, is the fuel in the vent line at that same
elevation as above?

Do you make a high spot in the header tank to plumb the vent tube
out of or does a flat top suffice for preventing a bubble on top? (i'm
picturing my cattle trough with a layer of ice on it when I fill it up. Air
gets trapped on the underside of the ice)

Could some photos or a drawing of the fuel system with a header
tank be posted please?

Thanks,
Paul SR074

When the engine is off, does the fuel equalize up the header vent to
the fuel level in the wings?

Do you need to create a high spot in the header tank to place the vent
or does the movement in flight push any air bubbles to the vent on a
flat top header tank? (Think filling frozen water trough when the hose
water breaks through the ice layer)

Does any one have any photos or sketches of a fuel system they can
post?
