Own it.
I'm not the only one to report that its included gasket leaks gasoline vapors and sets off check engine lights/produces diagnostic codes. 
I used the grease on the lock when I assembled it. Have had it on 2 Jeeps, never had that issue.Own it.
I'm glad if this hasn't been your experience.
Just because they're paranoid doesn't mean that the boogeyman isn't out to get them.
You're betting that a saboteur carrying around a bag of sugar (or whatever can make it through the maze of the fuel filler neck) doesn't have a screwdriver to pop open the fuel door?Mike, if one were to take the cost of someone pouring something really potentially damaging into the gas tank, multiplied by its likeliness, I believe that that cost (it's expected value,) as you say, to be demonstrable less than the costs of this:

let alone this Lastsun device.
Logically, you are in the right.
So why would I consider buying it, living in a safe area with no enemies?
All I can say is the peace of mind of knowing, in light of the seeming majority of ICE vehicles with locked gas cap access, makes my Wrangler less of a target for such random violence and some how gives me when less thing to worry about in a climate where the current state of affairs (not to get political) already gives me cause to loose sleep.
That is takes my odds from your .00001% to .000000001%, yep. I would be buying peace of mind, even if it's a false sense of a fool's paradise.
Funny logic coming from a guy who urges people using math not to be an extended warranty. based on statistics. But such warranties are far more expensive, and with far more loopholes.
This is a one shot done deal from a guy sick of getting EVAP codes from his MOPAR matching key gas cap with the lousy and leaky O ring.
..haven't pulled the trigger yet.
You can't argue the locking gas cap or fuel door doesn't work when they've never had anything poured into their tanks? Neither has anyone else, but ignore that anecdote.
The case I'm making for locked fuel access, is that I'm betting on a potential saboteur of my vehicle being a random attack (which let me be the first to say John is a rare event for anyone) that when they see restricted fuel access move on to the next (unrestricted fuel access) Wrangler in the lot (which most of them will be), of which in a lot of 100 cars in my area, 14 of them seem to be Wranglers, and most of the rest of the non Wranglers have some sort of restricted fuel access.
In this fantasy land they will see the "locked" door as just another challenge and specifically target you to become the OMEGA Saboteur that all other fictional Ne'er-do-wells aspire to be.
Hey come on give the guy a break, he makes a lot of good points. After reading through this thread I have decided to live, work, sleep in my jeep with my loaded 45. We live in a world where evil doers are just looking to get our gas or at least ruin our gas. I can't live like that anymore. I'm asking all of us to rise up and live in your Jeep!! We are at great risk due to the fact we do not have lockable gas caps/doors from the factory!!! Take up arms brothers!! Damn those saboteurs!
I don't think restricted fuel access is as common as you think. Many of the cover flaps are just spring loaded (my gladiator and the Ford escape work car I had as examples) where you just push in and it pops open. My prius company car has a release button inside. I'd say it's 50/50 at most.
It could be that the lock inspires the vandal, but it doesn't, sitting behind a gas cap cover at least in my case, likely draw them in.
It’s true, I think OP has an unfounded belief that most newer cars he sees with gas filler covers have an internal release button. I’d be curious if (prior to being arrested) he walked through this imaginary parking lot fully of nefarious sugar saboteurs and pushed on each gas filler door how many would open, then how many don’t even have a true gas cap but just a spring loaded cover just big enough to accept the filler nozzle. I won’t contribute to his criminal defense fund either. My vote, spend your money and actually do what you’re proposing or let this hypothetical problem go.
