a) Install a new sealing sleeve on the injector (if you filmed).
b) Apply a thin layer of fuel (lithol) to the new O-ring and install it on the injector.

c) Rotate the injectors and insert them into the fuel manifold.

d) Install (better stick it) four insulators and two spacers.

d) Install the injectors together with the fuel manifold onto the intake manifold. Gradually tighten the bolts securing the fuel manifold to the intake manifold.
4A-FE, 5A-FE, 7A-FE
3S-FE, 4S-FE
e) Make sure that the injectors rotate in their seats without sticking.
Note: If the injectors do not turn, the O-rings may be installed incorrectly. Replace the O-rings.
g) Install the injectors so that their connectors are on top.

c) Bolt the fuel manifold to the cylinder head.
