Review on Stant 10704 Fuel Cap by Shawn Quick

Replacing an old, leaking or missing gas cap can save up to a gallon of gas every 15 days and pay for itself in less than three months. Stant gas cylinder caps meet or exceed original quality and safety standards. The petrol/fuel filler cap performs three very important functions; Vehicle occupant safety, fuel economy and emission reduction. Safety: Without a gas cap, petrol fumes are always present around your vehicle. These fumes can be ignited by an accidental spark or flame and are very dangerous if you are involved in an accident or roll over. Fuel Economy: According to a Sun Oil study, a car with a missing or malfunctioning gas cap evaporates 176 pounds (22 gallons) of gasoline in a year. Emissions: Gasoline vapors release hydrocarbons that deplete the Earth's ozone layer and cause smog.
