I have original pumps, flying since 12/94 with about 1000 hours and no
problems.  My pumps are under each seat moving fuel up poyurethane lines to
the header tank, one for each wing tank.  I time transfer carefully,
alternating tanks about 5 to 6 minutes each to keep the header between 7 and
9 gallons and logging (pencil and paper) the minutes.  Transfer is at a rate
of .45 gpm so I know pretty well when each tank empties.  Also I built in a
spot where I can view the fuel lines to the header at the side of the stack
and when empty, air bubbles are clearly visible.  Unless sound asleep, one
cannot miss a wing tank emptying.  My fuel tank probes are very inaccurate.
Header tank fuel level is indicated by a clear polyurethane tube up the left
side of the stack, marked for fuel remaining.  Simple, no lasers, no fuel
selectors, no flowmeters, no complexity, and it works good and lasts a long
time.
