Fuel Delivery System

A fuel return system is used on all models. Fuel is returned through fuel pressure regulator within fuel pump module. The fuel tank assembly consists of: fuel tank, filler tube, fuel gauge sending unit/electric fuel pump module, rollover valve, ORVR control valve, fuel fill check valve, and a pressure-vacuum filler cap.

Also to be considered part of fuel system is evaporation control system. This is designed to reduce emission of fuel vapors into atmosphere. The description and function of Evaporative Control System is found in Emission Control Systems.
