• Twist the cap to the right until it clicks or it comes to a stop.
• While holding the cap, insert the key and turn it to the right about a half a turn until the key can be removed.
• When the cap spins freely, you will know the cap is locked and your fuel is protected.

There may be times when you do not want to lock your fuel cap. A competitive advantage of the FVP locking cap is that it can be used in the locking or non-locking position. When the key is turned to the left and removed, the cap is unlocked and no longer spins freely.

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
