The philosophy is that it is best to end a flight with all of yoy=ur
available fuel in a single tank, to prevent starvation at critical
times. On the old, pressure-carburetor Bonanzas, the fuel return fed
back to the left main tank only (about 2-3 gph). The procedure was to
run that tank dry, switch to the aux tank(s), run dry, switch to right
main an run it dry. You are left with an hour's worth of fuel in the
left main and no longer have to switch tanks for the duration of the
flight.

Unless the fuel return didn't function properly (can you preflight it?),
in which case you have zip.
