For a 75 mile non stop cross country flight I made successfully (on the second attempt) seven maybe eight years ago, I used stacked plumbing with three conventional tanks. A twelve ounce in the nose, a fourteen in the radio compartment near the CG and a twenty four ounce rubber banded on top of the wing on the CG. The power was a K&B .45 with a Perry, Varsane, Conley VP-20 ossilating pump mounted to the back plate. Not the VP-40 regulating pump.

Above wing tank fed the radio compartment tank and this tank fed the nose tank which fed the inlet to the pump and then to the carb. Muffler pressure was routed to the above wing tank.


This setup worked well and made the flight along old Route 66 possible.
