Fuel Tank: 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. The tank is made from High density Polyethylene (HDPE) material. If equipped with ORVR (Onboard Refueling Vapor Recovery) it has been added to the fuel tank to control refueling vapor emissions.
The PZEV (Partial Zero Emission Vehicle) fuel tank is a steel tank with the check valves, and hoses inside of the tank. This system uses the NVLD (Natural Vacuum Leak Detection) system for leak detection for both plastic and steel tanks.
