LOOKS GREAT AND SECURES YOUR GASOLINE

I recently had my gas tank syphoned!!! yes, at a 1.40 liter up here in Canada....I am not surprised it happened. And no I don't have the Trailer Park Boys as neighbors. Thankfully no damage to the internals ...

    Billet Locking Fuel Cap

    Product works well and looks very good. However the lock was very stiff and turns counterclockwise. Better instructions would have been helpful. I was concerned that the key would break off in the lock.

    LOOKS GREAT AND SECURES YOUR GASOLINE

    I recently had my gas tank syphoned!!! yes, at a 1.40 liter up here in Canada....I am not surprised it happened. And no I don't have the Trailer Park Boys as neighbors. Thankfully no damage to the internals or further mischief. So with this in mind I bought this locking gas cap, looks great and is strongly recommended.

    High Quality "Locking" Cap

    This is a heavy duty, sharp looking "locking" fuel cap. It is a two-handed operation, the cap will spin freely when locked and you need to hold it immobile with one hand and use the other hand to turn the key. I am perfectly fine with that. I wanted a locking cap. The handful of negative reviews seem to be based on the locking function but that is what it is. Understand before you order it that it is a locking cap. It is well built, has an excellent lock and looks sharp but if you are want to pass on the locking function it may not be the cap for you.

    Protecting your engine

    So you've spent tons of money perfecting the looks of your pony and spent tons of money building up your motors HP. Looks great and runs like a lightin bolt. The someone who's jealous or just wants to get back at you SUGARS your gas tank! This locking gas cap will rid yourself of that worry. No modification needed just remove the stock cap and install this one and you can sleep with no worries.

    Great quality, Great appearance

    Looks great, little bit of a pain at first screwing on and off but once you get used to it its no problem. Locking feature is nice but I don't use it. Combined with the Shelby Fuel Door really fine tunes the look. Didn't seem like that big of an appearance upgrade at first but once I installed them both I am glad I did. Other mustangs without seem to be bland and lacking.

    Great Looking and Locking Fuel Cap

    I bought this fuel cap because as you all know our fuel doors don't lock. I did not want anyone messing with my fuel. I've heard stories of sugar in the gas tank, water, etc. And that's the last thing you want to worry about. Do instead of getting a plastic dinky one, I got this. Feel, fit, and finish are great. But there are only two things that bug me, when you screw it on, it engages/locks in two revolutions. Its not like the stock one that you turn 3 times or so. Its just a mental thing that makes you think its not fully seated/threaded. But I have had no issues in 2 months. The other is the locking part. You need two hands to lock and unlock it. As when its locked, it spins freely, so you have to hold it with one hand and turn the key with the other. That's it... It works and keeps your fuel safe.
