CE ENGINE FUEL SYSTEM
Removal and installation
1. Check the fuel supply pipe for damage and
signs of leakage.
Leakage in the fuel supply pipe can be
recognised by erosion tracks (lines) on the
nose of the supply pipe. If necessary or if in
doubt, replace the fuel supply pipe.
Note:
2 If any indications of leakage are visible,
remove the injector and check the injector
fuel connection for signs of leakage.
2. Fit a new O-ring on the fuel supply pipe.
3. Apply a thin layer of clean engine oil to the O-
ring of the fuel supply pipe, the screw thread
of the nut and the contact surface of the nut
with the fuel supply pipe.
4. Check the bore of the fuel supply pipe for
foreign matter and damage. Also check
whether the supply bore in the injector is
correctly positioned for the bore, because it
is possible to mount the injector turned
through 180 , so that the fuel supply port is
on the other side.
Note:
The fuel supply pipe has one or two positioning
balls. The fuel supply pipe can only be installed
with the ball(s) on top, as the bore in the cylinder
head has a groove (1) at the top. Press the fuel
supply pipe as far as possible into the bore, with
the ball pointing upwards. Ensure that the O-ring
is not damaged in this process.
