An improved refueling system is provided for faster and safer pit stop refueling of a race car during a race, wherein the system is particularly designed for faster gravity drain flow to fuel from a pitside fuel tank to a fuel cell on the race car. The refueling system comprises an improved fuel nozzle adapted for quick and easy engagement with a mating receiver on the race car. In the course of engaging the fuel nozzle with the receiver, a flow control valve in the nozzle is moved to a full-open position defining a substantially unobstructed flow path for fuel flow through the nozzle at a substantially optimized flow rate to achieve refueling of the race car in the shortest possible time. The fuel nozzle is quickly and easily disengaged from the car receiver, and such disengagement is accompanied by automatic independent closure of the flow control valve. The refueling system additionally includes an improved overflow vent valve for opening a fuel cell vent port during refueling of the car, and for recycling vented fuel to the pitside tank.
