I planned on putting the wing tanks in the stub wings. Outter wing tanks
didn't ever get my attention and as stated it add's stress onto the WAF's.
If I put 7 gallons in each wing and then my 5 gallon header tank I will have
myself a 2 hour airplane with a 45min reserve. My corvair is expected to
burn 7GPH @ 75%. The lancair that I have flown in had sight tubes for each
wing tank on the line going to the header tank and the normal header tank
sight tube.
Undecided on how I will rig the wing tanks going to the header tank.
Rather I want the engine driven fuel pump to pump it all the time or have a
float type deal in the header tank. Im thinking more along the lines of it
filling all the time, i can see airbubbles when I know it's empty. Would
fuel guages be required in the wing tanks?
