ABSTRACT:
A mounting arrangement and method for installing fuel injectors in a molded composite intake manifold having an integral fuel rail portion in which the injectors are first assembled into bores in the fuel rail portion, and the intake manifold advanced onto a cylinder head surface having bores extending perpendicularly into the surface so as to allow the tips of the fuel injectors to be seated therein at the same time as the manifold is mounted. Air assist passages are also integrally formed in the intake manifold aligned with passages in the cylinder head.
