Anti-theft fuel caps

Best bet is cameras.

Anti-siphon and locking caps won't stop someone if they really want your fuel. Those things just make thieves damage your truck even more to get what they want. I've seen the aftermath of a theft where locking caps were used. The thief used something sharp and heavy to knock a 3/4" hole in the side of a tank. I would imagine it was something like a sledge hammer with a punch welded on it. Or a pick axe.

 

How can cameras stop a thief? A camera is used after the fact.

 

Yup. You catch one or two on camera and word will spread. Shoot, just putting up signs that the property is under video surveillance can go a long way.

 

A big set of channel locks can make quick work of locking fuel caps. The end of a sledge hammer handle will knock the anti siphon device down into the fuel tank. That's if they don't decide to knock or drill a hole in the tanks like someone else said. I have little faith in cameras or police after years ago a straight truck tore the hood off a brand new company truck I had parked in a truck stop. There were witnesses. Nobody saw a thing though, lol. The camera got some grainy footage of the whole thing. And the cop says sorry nothing we can do. They're going to get it if they want it. The best protection I have ever seen if your equipment is in your own fenced, locked up property is a mean assed junk yard dog trained to attack strangers.

 

duct tape an a couple razor blades on the top back side of the fuel cap get there attention

 

Completely understand that feeling , but is a good way to get sued. Till he starts stealing , he/she is only trespassing . They get hurt by a booby trap , you may well be in more trouble.

 

Only thing worse than a fuel thief is a sloppy fuel thief!
