This inner gas cap installs at the fuel filler opening behind the exterior pop-open gas cap cover. On compatible 1967-1970 Mercury Cougar applications, it serves as the functional fuel filler cap while maintaining the vented configuration used with this style of cap assembly.
A worn, damaged, incorrect, or missing inner cap can leave the fuel filler area incomplete and may prevent the fuel cap assembly from functioning as intended. Because this is a vented cap, it should not be used on 1970 Mercury Cougar applications equipped with evaporative emissions.
Complete the pop-open fuel cap assembly on your 1967-1970 Mercury Cougar with this vented inner gas cap for compatible applications not equipped with restricted 1970 evaporative emissions.
