Thanks Bob,
My tanks are a little different than yours but the info still helps.
Best,
Randy.

Randy:
My 235 has a 2-way fuel selector (wings/nose/off). In the 235 wing,
the D-section is the fuel tank. The pickup is at the aft inboard
corner, just in front of the spar. I routinely run the wings completely
dry before switching to the nose tank in flight. The engine is starved
of fuel for about 3-5 seconds. I have not found that any amount
of slip has caused unporting. Your mileage will vary, as you
have a completely different fuel tank location and shape.

Each wing tank is connected to a rattle pump and check valve.
The output of the check valve goes to the selector valve, and also
to the header tank. Turning on a pump transfers fuel from the
respective wing to the nose. So far, I have no complaints since
switching to this system.


BTW, here's a link to an earlier thread on what could happen if the
three-way-valve leaks:
