Mark, My setup is a bit different.
- Only the header tank has a filler; you fill the wing tanks through the header. - I have one return line going to both wing tanks with a tee. - A 3/8" works well - The header tank is vented through his cap. Remarks: if you have caps on your wing tanks, and if they are vented, the situation is different. You must prevent any flow back to the wing tanks, otherwise they will overflow by gravity. Hope this helps.

The fuel lines from the wing tanks to the header and to the carb are all 3/8". I have some questions. 1) Should the header tank have a fill cap? 2) Should I have one return line to each wing tank or would one line with a Tee in it suffice? 3) Should the return line be 3/8" or larger (like 1/2")? 4) Should I vent the header tank? Each wing tank is independently vented.
