Convenient Kits 
Available individually or in kits including transmitter, gasket(s), and screw/seal assemblies as applicable.


*** Installation Warning ***

Do not replace the Rochester fuel quantity transmitter with the Stewart Warner transmitters. The electrical function is not compatible. Stewart Warner transmitters must be used to replace Stewart Warner transmitters only. Replacing the Rochester transmitter with the Stewart Warner transmitter will result in erroneous fuel quantity indications.

Some Cessna and Piper aircraft have been modified with a Service Kit to use the
Rochester fuel quantity indicating system. This modification required changing the fuel quantity gauge, transmitter, and other electrical components. Do not use the McFarlane (Stewart Warner) transmitters as a replacement for these aircraft.
