I have a locking cap on all 3 of my cars due to that we have a troublesome neighbor who may attempt to drop something in my tanks. $9 bucks rockauto.com

 

as stated in an earlier post, ive been told by a "mechanic" at a stealership that there is a screen in the fill shaft that prohibits syphoning. besides if you wereto look at mine fill tube its rubber. so all a thief would have to do is cut the line in front of the rear tire and syphon the gas that way. or of course just poke a hole in the tank. theyll get it if they want it.

 

What was your neighbor putting in your tanks?

 

People by nature take the path of least resistance and choose soft targets. So if there's 20 cars on your street why go through all that extra trouble...when they can just move on and try a different vehicle. Same thing goes for your home....get a few big dogs while letting it be known that you're armed and I bet your anti-gun neighbor with a chihuahua gets robbed before you.

 

I picked up a chrome gas door; I like the way they look on a truck, so I went ahead and got one with a lock on it. I doubt it will stop anyone who really wants to get in, but I just hope it will discourage the random guy who has his car parked beside my truck. I wouldn't have worried about it if I were staying back home in Alabama, but since I was taking the truck back down here to Miami, I got the one with the lock. Maybe the "path of least resistance" rule will make the gas thief hit up the Chevy 1500 3 spaces down instead of my Ram.
