Capless Fuel System Compatibility

One of ITW's own innovations the capless refueling system, which garnered a Chicago Innovation Award has created a new standard in auto manufacturing.


This break-through system reduces evaporative emissions at the pump. Not only is it better for air quality, it’s also better for users: no more petrol odour on hands. Since there is no cap, users will not lose the cap, forget it at the gas station, or drop the cap and watch it roll under the vehicle.


No dangling cap means fewer paint scratches and the unique design of the fuel filler reduces the chance of gas syphoning.


For people with arthritis or other impairments, capless fuel filling brings welcome relief from the awkward or painful twisting to unscrew the cap.

  • Designed to make filling up fuel easier, once the fuel flap is open, there is no need to remove the fuel cap before inserting the pump nozzle

  • Instead, the hose is inserted directly into the filler

  • A small spring loaded flap in the filler neck prevents gas fumes from escaping the tank. This may reduce fumes as there is no waiting between the time the nozzle is removed and when the tank is sealed

  • Ford was the first manufacturer to introduce a system, and has now been followed by the likes of Jeep, Honda, Chevrolet, Volvo and GM
