DESCRIPTION
The fuel tank is constructed of a plastic material. Its main functions are for fuel storage and for placement of the fuel
pump module, and (if equipped) certain ORVR components.
OPERATION
All models pass a full 360 degree rollover test without fuel leakage. To accomplish this, fuel and vapor flow controls
are required for all fuel tank connections.
Two check (control) valves are mounted into the top of the fuel tank. Refer to Fuel Tank Check Valve for additional
information.
An evaporation control system is connected to the fuel tank to reduce emissions of fuel vapors into the atmosphere.
When fuel evaporates from the fuel tank, vapors pass through vent hoses or tubes to a charcoal canister where
they are temporarily held. When the engine is running, the vapors are drawninto the intake manifold. Certain mod-
els are also equipped with a self-diagnosing system using a Leak DetectionPump (LDP) or NVLD Pump, and/or an
On-Board Refueling Vapor Recovery (ORVR) system. Refer to Emission Control System for additional information.
