Fuel Tank

The fuel tank is constructed of a plastic material. Its main functions are for fuel storage and for placement of the fuel pump module. All models pass a full 360° rollover test without fuel leakage. To accomplish this, fuel and vapor flow controls are required for all fuel tank connections. A fuel tank check valve(s) is mounted into the top of the fuel tank (or pump module). An evaporation control system is connected to the check: valve(s) 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 drawn into the intake manifold.
