Review on Stant Flex Fuel Regular Locking Fuel Cap in Vibrant Yellow - Secure Your Vehicle's Fuel System by Troy Hamilton

I only bought this to add some yellow to my 2012 Jeep Rubicon and because I had a check engine light. After diagnosing the Jeep, it turned out that was the problem, why not yellow? Put on, blocked and switched on - the engine light is off! The lock is a bit more complicated but works great once you learn how to use the keys. Great product and I highly recommend it!
