Abstract
Various methods and systems are provided for reducing pressure in a fuel tank of a fuel system of an engine. In one example, cooling fluid is routed from an air conditioner of a cooling system to a vapor cooler disposed in a vapor space of the fuel tank such that fuel vapor in the fuel tank may be condensed and routed to a fuel pump for delivery to the engine, thereby reducing a fuel tank pressure.
