    1. Works as described.

      I have no problem installing this and despite being back ordered, still received it in a reasonable amount of time.

      I have had great customer service from these guys!

    3. Locking fuel cap.

      I love the locking fuel cap !!!
      That being said it took me weeks to get. It came with no keys. Cost me $7.20 to return it, to wait 2 more weeks to get a replacement. And no refund on me having to ship the cap back to the military guys for replacement.

    4. Fits perfective

      Just as advertised. Great replacement since personnel lost the last one. on 22nd Feb 2017

    5. Awesome Cap

      I give it 4 stars because it's tough to screw on and seems as though the threads are catching, but outside of that it's secure.

      I would check your filler neck to see if the threads might have a little damage maybe take a small file to the threads and clean them up.
      thank you

    8. keep your fuel safe

      handy product to protect your fuel tank
      easy instal
      needed slight adjustment on the internal lock since it would keep hanging on the internal housing while rotating the cap open
