Fuel Charging Wiring Harness
The fuel charging wiring harness links the fuel injectors to the engine management system.
Fuel Pressure Regulator
The fuel pressure regulator is a vacuum operated, spring loaded diaphragm type and is designed to maintain a constant fuel pressure in the fuel injection supply manifold with excess fuel being returned to the fuel tank. Sealing is achieved by means of two O-ring seals.
Fuel Injection Supply Manifold
The fuel injection supply manifold is a one piece plastic moulding with holes for the fuel pressure regulator and the fuel injectors. Sealing is achieved by means of six O-ring seals.
Throttle Body
The throttle body is of aluminium construction with a hole for the throttle position sensor. Sealing is achieved by means of a gasket and an O-ring seal.
Fuel Injectors
The fuel injectors are of the top feed type. They are activated sequentially by the powertrain control module (PCM) which modifies fuelling by adjusting the fuel injector opening times according to engine operating conditions. Sealing is achieved by means of upper and lower O-ring seals.
