Now you can refuel your car quicker and cleaner by replacing your old gas cap with the cool new InStant Fill Fuel Cap. Rather than having to handle and remove the cap each time you gas up, simply insert the nozzle through the InStant Fill's trap door mechanism and squeeze the trigger. There are four different InStant Fill models that fit over 80% of the cars on the road in North America, it meets all onboard diagnostic (OBD) emission specifications and will not trigger the check engine light on late model vehicles. Great solution.
