3. Locate the four injector harness pigtails. These need
to be connected to the fuel rails (Figure 5).
4. With the brackets and injector pigtails installed on the
intake manifold, it is time to install the injectors to the
fuel rails. Apply a dab of engine oil to the o-ring seals
of the injectors. Insert the injector with its connector
facing towards the outside of engine into the fuel rail.
Install the injector retainer securely and check that it
is properly installed and sealed to the rail (Figure 6).
Continue with the other three injectors.
5. With the injectors installed, it is time to install the fuel
rail assembly to the engine. Position the rail assembly
over the intake manifold with the injectors aligning
with their mounting pockets on the intake (Figure 7).
6. With the injectors lined up, lightly press down on the
fuel rail using caution not to bind any of the injectors
or connectors. The fuel rail assembly should come
close to contacting the manifold brackets with very
little pressure. Use caution not to bind or tear any
injector O-rings.
