For Dave Saylor:

Dave:

I had to cringe when I realized the bag of worms that you seem to be getting yourself into feeding fuel into a partially empty wing tank.  Im not saying that it cant be done but.......?

Have you considered plumbing your aux tank directly into the unused (3rd) fuel inlet on the standard lancair fuel selector??   This might eliminate many of the concerns that your presently facing.   Maybe an additional fuel pump just in case???

Just a thought.

P.S.  Would like to hear the final outcome, if possible.
