3. Lower the filter bowl and element and discard
the fuel, together with the old element.
4. Thoroughly clean the filter bowl in cleaning
fluid.
NOTE: Do not use gasoline as a cleaning fluid.
5. Place the new element and sealing rings in
position, fill with clean fuel, and push the bowl
up firmly and squarely so that the top rim of the
filter element locates centrally against the
sealing ring in the filter head.
6. Hold in this position while the securing bolt is
located and tightened. If the bowl is located
correctly, no excessive tightening will be
required to obtain a leak---proof seal.
After the fuel filter has been reassembled, it is
necessary to remove air from the fuel system. See
Bleeding Fuel System.
FUEL INJECTION PUMP
The fuel injection pump controls the engine speed.
The maximum speed screw is set and sealed by the
manufacturer and must not be altered in any way
unless factory authority is first obtained. Any
adjustments should be carried out by experienced
fuel pump technicians. The unauthorized removal of
any seals on the pump may void the warranty.
ATTENTION! Unless proper test equipment and
trained technicians are available, adjustment or
maintenance of the fuel injection pump should not
be attempted.
FUEL INJECTORS
When replacing injectors in the cylinder head, it is
essential that a new, correct---type heat shield
washer be fitted between the nozzle cap and the
cylinder head.
Care should be used when replacing the fuel
injectors to prevent loosening the injector leak---off
nipples.
Be sure to cut a relief in the inside of your socket for
clearance. This will prevent an interference between
the socket and the leak---off nipple.
