A number of variations may include a product comprising: a mechanical seal fuel fill system including a fill line for transporting fuel into a fuel tank. The fill line may be operatively connected to a fill cup to receive a fill nozzle. The fuel fill system may also include a vapor canister to receive fuel vapors displaced during refueling from the fuel tank. The vapor canister may be fed via a canister vent valve inside the fuel tank. The fuel system may also include a recirculation line connecting the fuel tank to the fill line. The recirculation line may include an auxiliary valve in the fuel tank. The recirculation valve and the auxiliary valve may be in a parallel arrangement.
