92 Unscrew the fuel line banjo unions from
the filter, which is located in the right-hand
rear corner of the engine compartment. Be
prepared for some loss of pressurised fuel,
and mop it up with rags.
Fuel pump
93 The fuel pump can be removed from its
location beside the fuel tank after
disconnecting the fuel hoses and wiring plug,
and then releasing the mounting clamp.
Refitting all components
94 Refitting of all components is a reversal of
removal, but observe the following points.
95 Use new seals and gaskets as applicable,
noting that three rubber seals are used on
each fuel injector and insulator (photos).
96 Adjust the throttle position switch as
described in paragraph 46 of this Section.
97 When refitting a new fuel filter, make sure
that the arrow marked on it is in the direction
of the fuel flow.
98 Apply gasket cement to the threads of the
coolant temperature sensor.
Throttle control linkage -
general
99 This is of the cable and rod type. Adjust the
cable by means of the end fitting and nut, to give
the slightest play in the cable when the plastic
socket is engaged with the ball on the link rod
which runs across the camshaft cover (photos).
100 Keep the cross-shaft pivots and return
springs lubricated.
Fuel tank - general
101 The fuel tank is of metal construction, but
note the plastic anti-blow-back compartment
between the filler cap and the tank. This is
accessible from under the right-hand wheel
