12.2 Engine compartment
a) Fit fuel lines from carburettors and a T-piece in the pipe as shown in Fig 216
Remember to slip the appropriate pipe clips over the pipes.
The fuel pipe joining the two carburettors can be conveniently clipped to
the intake manifold balance pipe.
Figure 223 fuel pipe routing in engine compartment.
b) The standard T-piece is connected to a short length of fuel tube running
forwards approximately half way to the fuel pump outlet.
c) At this position a T-piece with a restrictor connects to allow the anti-vapour
lock fuel return line to pass neatly behind the gearbox, Figure 216.
This restrictor should be a precision Rotax/Skydrive item.
d) The front of this T-piece then connects to the fuel pump outlet (the smaller
diameter pipe spigot on the pump).
e) The fuel supply pipe from the tank connects to the inlet of the fuel pump (the
larger diameter pipe spigot on the pump).
Note that although the fuel pump inlet and outlet tubes are of different
diameters, the fuel tube will fit over both of them.
A useful tip: to fit ¼” bore flexible rubber pipe to 8mm metal tubes
tenderise (as per a steak) the end of the rubber pipe, or heat it by
dipping into boiling water. This softens the end. Then with a small drop
of light oil (3-in-1) placed on the tube or the pipe, slip the rubber tube
over the metal pipe. A slightly larger pipe clip (no13,14 or 15 depending
on fuel line wall thickness) should be used.
The fuel supply pipe and the fuel return pipe both pass behind the
gearbox and back over middle of the engine and under the centre piece
of the engine mount, to pass through the firewall beside the rear of the
starboard upper engine mount. Make sure the holes in the firewall are
edged or grommeted to prevent the fuel lines from Chafing.
