O.S. Engines 160FX-FI - Manual (Page 12)

•Make connections in the following order: Engine (carburetor nipple), check valve (provided),
T nipple and fuel tank (air chamber side)
•Make connections in the following order: Injector, fuel tank (provided), T nipple and fuel tank
(weighted side)
NOTE:
Always make sure to release any pressure remaining in the tank when adding fuel and
following engine operation.
Silicon tubing is easily damaged by sharp objects that can lead to the formation of holes and
cracks. Check the surrounding area of the presence of potentially harmful sharp objects.
A soft engine mount is recommended but should be made of firm enough meterial to prevent
excessive engine movement but still minimize engine vibration. If engine vibration is excessive the
opening angle of the air valve may vary causing unstable engine operation and possible stalling.
In addition, adequate clearance must be provided to ensure there is no contact between the
injector, temperature sensor and rotation sensor with the airframe.

Connect all lines securely as shown in the figure above. Since high pressure is applied to the fuel
tank from the engine crankcase, make connections using a commercially available, thick-walled
silicon tube. In addition, make sure to securely seal the area around the cap. If the outlet of the T
nipples is left accessible from outside the airplane, it will make venting tank pressure and refueling
easier. Always make sure to use the check valve and fuel filter provided.
