MotoRad fuel caps are designed and manufactured to prevent fuel loss primarily through evaporation. Additionally, MotoRad non-locking and locking caps are designed for easy opening and closing by all drivers, including people with smaller hands. They prevent fuel vapor leakage from the filler neck, which is a major source of hydrocarbon emissions, and play a major safety role in preventing the flow of fuel from the tank filler neck when a car is in an accident, including rollovers.

• Controlled pressure release allows slow release of pressure before removing the cap
• Integrated ratchet system promotes positive closure
• Passes all state and federal emissions tests
• Manufactured from durable, long-life materials
• Reduces air pollution with proper sealing and venting
• Independently tested for emission control

Caps with controlled pressure release technology allow pressure built up in the fuel tank on hot days to be released gradually when the cap is opened. This prevents fuel from erupting and spraying out on the motorist. Below are the three types of controlled pressure release cap styles (not all styles are available for all applications):

Push Vent
Push button to
release pressure

Key Vent
Push key into lock to
release pressure

Twist Vent
Push & 1/4 turn to
release pressure

The color of the cap can be used to identify the vehicle's fuel compatibility. The physical cap is the same, regardless of color.

Gasoline
Black is the standard
Fuel Tank Cap color for
vehicles that take Gasoline

Flex (E85) Fuel
Yellow indicates your
vehicle is Flex (E85)
Fuel compatible

Diesel Fuel
Green serves as a reminder
that your vehicle only
takes Diesel Fuel
