A choke for reducing spray of fuel exiting a fuel dispensing system nozzle spout having an annular frame positioned within the spout adjacent the output opening. The choke has a concentric hub connected to the frame by three, relatively narrow struts positioned equidistant around the hub. The hub has a solid, cylindrical fore section tubular aft section. A duct extends from the tubular aft section, through one strut and the frame, to the sensing port. Fuel flowing through the spout toward the output opening, it is slowed and divided into three streams by the choke, flows along the hub fore section and converges, compressed and linearly aligned, at the output opening of the spout to reduce spraying of fuel at the output opening of the spout and avoid unwanted shut-off.
