I have been flying my 701 for 8 years. I had uneven fuel flow like everyone else. I built a mockup with transparent tanks and 1/4 inch lines, and just sitting on my porch with no airflow pressures or forward facing vents or balance lines, I could see the same uneven flow tendencies. Little bubbles were forming and stopping the flow (but not sure that that is the problem with 3/8 lines). I put a small tv camera inside my full gas tank and found lots of bubbles in the finger screen. Don't know how they got there. Concluded that the only way to have control over the fuel flow was to have separate valves - one for each tank, so I now run the fuel lines under the seat to two valves on the floor, and then to the Aircraft Spruce gascolator forward of the firewall. I have total control. No more worry about an inadequate design. 912uls, no return line, original internally vented caps. I did have my green plastic alcohol resistant (from Spruce) fuel line disintegrate right at the wing root and spill ten gallons of fuel down the cabin side, through the baggage compartment and out the bottom onto the hangar floor . Changed to automotive rubber lines.
