Fuel Delivery

The fuel delivery system consists of a low pressure, in-tank fuel pump, a fuel filter/reservoir, and a high pressure electric fuel pump. The fuel charging manifold assembly incorporates electrically actuated injectors directly above each engine intake port.

When energized, injectors spray a metered quantity of fuel into intake air stream. The length of time that injectors are energized (injector "on time" or "pulse width") is controlled by EEC-IV module.
