With DVR this thing lets you see who tried to steal gas

 

I was thinking of getting straight up locking caps. If the guy is brazen enough to take off the cap to siphon fuel then discovers he can't, he may be evil enough to put other products in there that will cost way more than a tank of fuel to fix.

 

I think it would be an either/or scenario; either they are trying to steal fuel, or they are putting something into the tank. I put very little weight on the latter. I think most fuel is going to be stolen by opportunists who aren't going to waste time if they can't get at any. They might be inclined to throw a handful of dirt in, but I think that is about all.

I have had locking caps before and I don't think they provide enough value, but they do increase the PITA factor... especially when running in very cold regions.

 

In Europe they make a hole in your tank if they can't get through filler neck. That's the reason I don't use those antisiphon devices. I have 2 options, lose fuel or lose fuel and get a broken tank.

 

since now i have never heard for this

can you be more specific in which conturys ?

 

on some old trucks there were plugs on tank bottoms to drain water))) LOL

 

We use much more sophisticated anti-siphon fittings here in Southern Africa.
We had those spiral ones back in the early 80's.They are easily beaten by 3 or 4 medical size tubes connected to an electrical transfer pump.The ones we have have multiple holes of about 1/8" then another sleeve with the same holes but off set.You cant even feed a thin tube through it.

In certain country's they weld a inch long spike on to a jack. They then place this under the diesel tank and jack the spike in to the tank.Remove the jack then drain the diesel.
