Paul,

Here’s my new intake manifold. The runners have epoxy formed trumpet
mouths and I believe the air will flow nicely.



To header tank……. or not to header tank?

That is the question.

I guess this is more of a Cozy question than a rotary question.

Is the problem, fuel starvation from a long banking turn and all of the
fuel flowing toward the wing tip of the low wing and away from the tank
sump? Or is there also a problem with a long decent and the fuel moving
forward of the fuel pick up?



I am considering a simple fuel shut off ball valve remoted to the
cockpit. With a check valve in each tank feed (Aircraft Spruce part
number 05-00716) with another ball valve connecting the tanks around the
check valves on a spring loaded lever (so it can’t be left open) for
tank equalization if needed. This solves the banking issue but I wonder
if there is an issue with starvation on a long decent.



This keeps the header tank out of the cabin and maybe leaves me enough
room for a heater core. I am using a dead end regulator from Marren Fuel
Injection (visible in the photo on the firewall end of the fuel rail) so
I don’t need a return. (good idea or bad)?



What is the problem or draw backs with the original fuel system as on
the plans with lines coming up to the cockpit with fuel valve mounted there?


Any thoughts?
