FUEL CHARGING AND CONTROLS







The supply manifold is a fabricated plated steel rail with stamped cups for the injectors. The supply manifold is retained to the engine by two bolts.

The fuel pressure sensor is fitted directly onto the supply manifold and is retained by two bolts. Sealing is achieved by means of an O-ring seal.

The fuel injectors are fitted directly into the supply manifold and are retained by the supply manifold when assembled to the intake manifold. Sealing is achieved by means of upper and lower O-ring seals. The fuel injectors are activated sequentially by the powertrain control module (PCM) which modifies fuel quantity by adjusting fuel injector opening times according to the engine operating conditions.
