Fuel Delivery

DESCRIPTION AND OPERATION
The fuel supply is stored in the fuel tank. An electric fuel pump (inside the fuel tank) pumps fuel through an in-line fuel filter to the throttle body injection unit. The pump is designed to provide fuel at a pressure above the regulated pressure needed by the fuel injector. A pressure regulator keeps fuel available to the injector at a regulated pressure. Unused fuel is returned to the fuel tank by a separate hose and pipe.

Unleaded Fuel Only
This vehicle's engine is designed to use only unleaded fuel. Unleaded fuel must be used for proper emission control system operation. Using unleaded fuel will also decrease spark plug fouling and extend engine oil life. Leaded fuel can damage the emission control system, and its use can result in loss of emission warranty coverage.

Evaporative Emission System
This vehicle is also equipped with an evaporative emission system that minimizes the escape of fuel vapors to the atmosphere.
