 The power loss while switching tanks is repairable.  I had that issue for
 two years before I moved my fuel pump to the floor below the foot well on
 the right side of the plane.  Since having the pump rebuilt by Dukes and
 then moving it the issue is gone.  I have laid the pump on its side and it
 appears to work fine in that orientation.  I hope this helps.
