The float detached from the sender in the right main tank on the
PA32-300 I flew to Florida a year ago. The gauge was therefore inop.
The aircraft is equipped with a FS-450 fuel flow monitor. I used this in
place of the specific fuel gauge. The FS-450 is accurately calibrated to
within 0.2 gallons, much better accurate than the manufacturer's fuel
gauge.

Was I legal?

Offhand, I don't see why not. FAR 91.205b9 only requires a working
fuel gauge for each tank. It doesn't prohibit an additional, non-
working gauge.

Since the FS-450 isn't TSO'd as a replacement for the facotry
installed and required fuel guage, and carries a "Do not
rely on fuel flow instruments to determine fuel levels in tanks. Refer
to original fuel flow instrumentation for primary information."
warning in the pilot's guide, I do not belive your answer is correct.
