Dynon SkyView HDX - Fuel Pressure Sensor

SV-EMS-220 Engine Monitoring System Installation and Configuration
10-12 SkyView HDX System Installation Manual - Revision E
Another option for sealing the sensor to the engine case is Earl's Stat-O-Seal Sealing
Washer # 178010 installed between the sensor and the engine case.
Tighten the sensor according to your engine manufacturer’s recommendations.
Route the wire from a general purpose input pin on the EMS 37-pin Main Sensor Harness
to where the oil temperature sensor is mounted. When routing the wires, make sure that
they are secured, so they will not shift position due to vibration. Strip ¼” of insulation off
the end of the wire. Crimp a #10 ring terminal onto the end of the wire, ensuring that a
good connection is made between the wire and the connector. Unscrew the nut from the
stud on the oil temperature sensor. Slip the ring terminal onto the stud and secure the nut
over it.
10.2.13 Fuel Pressure Sensor
Mount the fuel pressure sensor securely to the airplane's structure using appropriate
AN/MS hardware fittings, clamps, and flexible hose. Do not mount the sensor directly to
the engine's pressure port. The pressure sensor has a 1/8-27 NPT pipe thread fitting.
DO NOT mount sensor directly to engine or other areas of high vibration.
Always mount the sensor to the airframe structure, and connect it with flexible
hose to minimize vibration effects. Avoid damaging plastic portion of sensor
when threading it into matching fitting.
Always use an AN/MS fitting with a restriction intended for pressure indication
systems when connecting sensors to a pressure port on an engine. Restrictor
holes minimize leakage in the event of a failure of any of the items
downstream of the pressure port connection, allowing time for an emergency
landing.
As of 2020, Dynon Avionics no longer supplies the original 0-50 PSI Kavlico sensor (P/N
503389-000). For new installations, For new installations, select the appropriate sensor
for the airplane's fuel system:
• Use the new 15 PSI Kavlico sensor (P/N 503850-000) for most carbureted fuel
systems with 0.6–15 PSI requirements.
• Use the new 150 PSI Kavlico sensor (P/N 503851-000) for most injected fuel
systems with 6–150 PSI requirements.
If both the 50 PSI and 150 PSI sensors meet the airplane's fuel system
requirements, then use the higher pressure 150 PSI sensor.
If neither of the above are suitable for the airplane's fuel system:
• Use the new 50 PSI Kavlico sensor (P/N 503983-000) for fuel systems with 2–50
PSI requirements.
