Installation Warning
Do not replace Rochester fuel quantity transmitters with the Stewart Warner transmitters. The electrical function is not compatible. Stewart Warner transmitters must be used to replace Stewart Warner transmitters only. Replacing Rochester transmitters with Stewart Warner transmitters 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.

Frequently Asked Questions
What is SEB99-18R1 about?
Cessna SEB99-18R1 describes periodic checks of the fuel gauging system.
Can I use a McFarlane transmitter on a Cessna 152 aircraft?
No, the fuel indicating system on a Cessna 152 is unique and McFarlane has not designed a transmitter for them yet. However, we do have replacement fuel quantity transmitter gaskets and screw seal assemblies available for this aircraft.
How do I keep contaminants out of my fuel system?
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources McFarlane recommends the use of a fuel filter, such as Mr. Funnel or another filtering device, to reduce trash in the fuel system.
