REFLECTOR: Low Fuel Warning Sensor False Reading: SOLVED?

[Scott Baker]

On a recent sump tank installation, found float switch to be unreliable 
(false signals).  Replaced with optical sensor, same result.  Then 
installed both!  Low fuel alarm must "pass" float switch and optical 
sensor "test".  No more false signals.
Overkill?  Yes, maybe.  Happy with results?  Yes.
