1.3.7 Installation of injection nozzles and manifold absolute pressure nozzles
Picture 1.3.33 Location for installation of nozzles
in the manifold (view from the outside)

In certain cases (see the appendices), it is necessary to remove the inlet manifold.
Orifices should be
drilled as close to the engine head as possible. Mount nipples in such a manner, as to makes sure they
point to the suction valves, and secure them against unscrewing. Connect injection tubes to the nipples
and secure them with a metal clamp.
Mount the injector on supports and connect it to the injection tubes. Subsequently, fit the supply tube
as well as the pressure measuring tube. Connect the wiring harness to the injectors, while observing the
order specified in the scheme.
NOTE! Nozzle sizes for particular types of engines have been specified in the appendices hereto.
The manifold absolute pressure nozzle should be installed in the shared part of the inlet manifold
(downstream the throttle).
