Fuel Pressure Sensor; Manifold Pressure Sensor; Miscellaneous Pressure Sensor; Engine Torque Sensor - Garmin G3X Touch Installation Manual

3. Connect the supplied connector to the appropriate inputs of the GEA 24/GSU 73 as referenced in
the Sensor Interface Drawings in Section 30 through Section 32. Secure the connector and wire
assembly to an appropriate location in the engine compartment to provide strain relief.

23.3.5.1 Fuel Pressure Sensor

Kavlico P4055-15G-E4A - 0 – 15 psiG pressure transducer for all carbureted engines.
Kavlico P4055-50G-E4A - 0 – 50 psiG pressure transducer for all fuel injected engines.
UMA N1EU07D - 0-7 psiD differential pressure transducer for certain turbocharged carbureted engines
(Rotax 914)
UMA N1EU35G - 0 – 35 psiG pressure transducer for carbureted engines.
UMA N1EU70D - 0 – 70 psiD differential pressure transducer for certain turbocharged fuel-injected
engines (Rotax 912iS/915iS).
UMA N1EU70G - 0 – 70 psiG pressure transducer for fuel injected engines.
NOTE
Lycoming EIS display ranges are typically set to correspond with the pressure at the inlet
to the fuel injector. Continental EIS display ranges are typically set to correspond to
unmetered fuel pressure values.
