System Description

Fuel Delivery System:

PURPOSE

Sequential port Fuel Injection (SFI), system, supplies engine with sufficient amount filtered fuel at correct pressure.

OPERATION

Electric pump pushes fuel through in line filter, to fuel rail, injectors (6), and pressure regulator.

Vacuum assisted regulator maintains pressure at injectors by allowing excess fuel to return to tank via return line.

Powertrain Control Module (PCM) controls fuel flow through injector by varying injector pulse width.

CONSTRUCTION

Fuel Delivery system consists of fuel tank, fuel pump, fuel filter, fuel rail, fuel injectors (6), and fuel pressure regulator.
