NEW LOCKING FUEL CAP
They have been setup to work on the M939 military trucks THEY ALSO WORK ON THE M1070 AND M1078 AND A FEW OTHER MV'S THAT USE THE 4INCH THREADED CAP
So if you value your fuel in your truck or don't want any unwanted items to be left in your tank we have the perfect solution for you.
These caps come with 2 keys and the chain so you don't for get it at the pump and for those who have removed the screen or dont have a screen we are suppling a metal retaining rod to hook to the chain to keep your cap attached to the tank.
2.5 ton owners: Fits only the m35a3 and m35a4.
Jim please contact us with a order number so we can correct this problem we have never had this happen before and we have sold a couple hundred but there is a first time for anything but we want to make sure the problem is corrected and you have what you paid for and is working correctly.
Lock doesn't work. put it on the truck locked it and the lock came apart. Screw in the bottom fell out. glad the grenade block was still in it, tried to put it back together but its broken. Jim on 3rd Oct 2017
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. Jim on 4th Sep 2017
Just as advertised. Great replacement since personnel lost the last one. eric on 22nd Feb 2017
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.

I've had this on my M923A2 and trust me when I say "don't lose the key" it's built just like my truck heavy and solid steel. J Pitt on 5th Nov 2015
Quick install. Positive ratcheting lock. Mike on 30th Jun 2015
handy product to protect your fuel tank
needed slight adjustment on the internal lock since it would keep hanging on the internal housing while rotating the cap open
it could be your screen in the filler neck is out of round alittle bit we have had one other person that had a bent screen art on 7th Jan 2015
Works Great Unknown on 30th Sep 2014
This fuel cap fits my M35A3 fuel tank perfectly. Works as advertised. Very easy to install. Protects against fuel thieves and vandalism. Thank you. Ernest Griess on 10th Sep 2014
Very nice product, a custom aluminum casting that incorporates the locking mechanism. It is a great design, one of those "why didn't somebody think of this sooner" things. Fits my 5 ton M923A2 perfectly. Comes with 2 keys, I've already made extra copies. Unknown on 3rd Sep 2014
