Fuel System - General Information

Fuel is supplied at high pressure to the fuel injectors through a fuel injection supply manifold. For vehicles without a returnless fuel system, the fuel injection supply manifold is equipped with a fuel pressure regulator. For vehicles with a returnless fuel system, the fuel pressure regulator is integral to the [1][2][3]fuel pump module. An inertia type fuel shutoff switch will cut power to the fuel pump in the event of an accident. The fuel lines are metal with flexible connections.
