Abstract:
An evaporative emissions control system configured to recapture and recycle emitted fuel vapor on a vehicle fuel tank is provided. The control system includes a first and second vent tube disposed in the fuel tank, a first and second vent valve, a vent shut-off assembly, a purge canister and a control module. The vent shut-off assembly selectively opens and closes the first and second valves to provide overpressure and vacuum relief for the fuel tank. The control module regulates operation of the vent shut-off assembly based on operating conditions to vent the first and second vent valves to the purge canister. The vehicle fuel tank comprises a saddle tank having first and second lobes and a raised portion arranged generally at a top portion of the fuel tank. The first vent valve is arranged generally in the first lobe and the second vent valve is arranged in the raised portion.
