There's an anti-siphon screen and the filler neck has an internal "maze" that makes it challenging to get crap in. That used to happen long before the current design of filler necks, but it seems to be incredibly rare now. But, of course, just because people are paranoid about this type of thing doesn't mean that someone's not out to get them.
I'm pretty sure that's no longer a real option via the fill neck.
Cause the lift, lights, winch and gear I have had a use for, have yet to have anyone steal my gas, or anything out of any of my cars for that matter and Ive lived in many different large cities that people are afraid of.
As I stated above, plastic tank and tall enough vehicle to roll under. It's quicker and easier to stab the tank with a simple screwdriver and throw a bucket under the Jeep. Who cares if 15 gallons of your fuel pours on the street after they get their 5 gallons? And if it's really just to destroy your vehicle, skip the bucket and throw a match under there instead. In my opinon you're just encouraging more expensive damage with your $25 locking gas cap, which is why I can't justify it.
Yes...I agree that this may be the case for gas theft, but I was referring more to the vandalism described in my previous posts.
I have seen both vandalism and fuel theft (via hole in gas tank) on a few occasions over the last 50 years. Not really urban myth, but it also isn't common. That said, it's $25 of insurance to avoid spending thousands on an engine replacement. If that makes you and I feel more secure when parking in a sketchy lot overnight or in airport parking for several weeks, then it's worth every penny IMO....and I am one cheap bastard!
The sugar would probably dissolve enough to get through into the engine, although I'm not sure you could dump enough into the anti-siphon filler neck to do anything. Sand? Please. Have you seen the filter sock on the pick up in the tank? It wouldn't pick up any sand. Even if it somehow did, the orifice in a fuel injector is far too small for a single grain to make it into the engine. It's a solution for an imaginary problem on a modern vehicle.
Was the vandalism with the newer anti-siphon filler necks?
Googled it to verify my suspicion that it's not much of a task concern on a modern fuel injected vehicle.
If your why's prove to be false on a modern fuel injected vehicle are they really a legitimate concern though? You can't just dump sugar or sand or even Pepsi down a modern fuel neck. Even if you did it would simply plug the filter not kill the engine. If it makes you feel better, do whatever makes you happy.
Siphoning was a thing in the 70s but as others have said it’s virtually impossible on a modern vehicle. During the “gas crises” in CA in the late 70s I did have someone siphon gas out of my 72 Chevy Nova. Probably about $2.00 worth of gas back then. My buddy and I (being young and dumb) saw him and chased him but he already was ahead of us and he threw the gas can and outran us.In all my years I've never read, heard or seen any reports of anyone doing anything about stealing ,siphoning, adding to a gas tank.
It's just a paranoid mindset that thinks this way.
Besides in NJ the only state where you have a attendant pump your gas , we usually don't touch that door.
I could imagine the attendant tapping your car every time you get filled up because you forgot to unlock the fuel door.
