The battery is disconnected.
The air-filter is taken out.
To disconnect:
-no. 1 fuel supply tube;
-no. 3 return fuel tube;
-no. 4 pressure-regulator tube.

RE-MO UNT ING
Replace t he t orric fittings at the base of
the i njectors (if t he i njector has been taken
apart as well a s the fitting at the end of t he
injector). For the supply junctions and the return
petrol tubes to be c orrectly coupled a click
must be heard the moment the coupling is
done.
