Abstract
A method for a fuel system, comprising: during a first condition, fluidly coupling a fuel tank to a fuel vapor canister; and fluidly coupling the fuel vapor canister to atmosphere via a deactivated vacuum pump. By fluidly coupling the fuel vapor canister to atmosphere via a deactivated vacuum pump, the fuel tank may be depressurized slowly without requiring a multi-stage or multi-valve fuel tank isolation system. In this way, the cost and complexity of the fuel system is reduced.
