Flexible lines
See Fig. 73-45
See SI-912-020, ”Running modifications”, latest issue.
From 2007 on, all new models will have a flexible line instead of the
present rigid fuel line.
Assembly at the carburetor should be carried out analogously the
diassembly. See sec. 3.4.4.
◆
NOTE: In case of a retrofit on configurations with steel fuel
lines remove the screw connectors (1) and remove
remaining sealant residues in a way that they do not get
into the carburetor or the fuel system.
For installation on an old style intake manifold perform the following:
- Remove the intake manifold and machine the nut/clamp contact
area until the surface is parallel with the sealing surface of the carb
socket. The thickness of the material must not be dressed down less
than 10,5 mm (0.413 in.) and should be smooth and flat so that the
nut/clamp assembly has an even contact surface (see Fig. 73-46).
- Ensure proper support of the flexible fuel line. Install Hex. screw (2)
and washer (3) with 15 Nm (133 in. lb.). Install the cable clamp (4)
at the hex. screw (2) of the carburetor socket with the hex. nut (5).
Tightening torque of hex. nut (5) 24 Nm (18 ft. lb.)
