O.S. Engines 140RX-FI - Manual (Page 12)

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.
•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 manifold exclusively for OS use is available. Make sure air flows smoothly by giving
consideration to the air intake and outlet so that warm air does not accumulate in the engine
and muffler cowling. In the case of using another manifold, make sure that the inner diameter
and length are the same as those of the OS manifold.
A tuned silencer is available for use with the OS MAX-140RX and 140RX FI.
Always make sure to use the genuine T-6010 silencer.
Install the EC-1 in a location that is not susceptible to the effects of heat, fuel or vibrations while
allowing easy manipulation. Always make sure to attach double-sided, sponge-backed
cushioning tape or Velcro tape between the airframe and EC-1 as measures against vibrations.
Ensuring a proper linkage is important in the 140RX FI system in terms of a proper air-fuel mixture.
In other words, it is necessary to maintain the proper relationship between opening of the air valve
(stick position) and fuel injection by the injector.
