Hi Steve,
Just for comparison -my fuel system is very similar in concept. The principal conceptual difference is I have a header tank for return of my fuel from injectors mounted on the fire wall and is ½ pint in capacity. The theory is not much fuel to have to get rid of if it gets hot. The fuel flow into the engine through the injectors continuously pulls cool fuel from wing tanks.
8 gallons of hot fuel (if it ever got hot) might take a while to burn down to the point the cool incoming fuel does some good.
This size goes counter to “tradition” on size of header tanks but is more in line with the “returnless” systems on most of today’s automobiles.
FWIW

Hi All
We are trying to make a decision re: fuel system.
I’ve attached a PDF with design and questions etc.
Could you please pull it to pieces, make recommendations?
Steve Thomas can you comment also from the GSIIRG perspective?
Thanks
