Interesting design in new anti-siphon unit

None on my 379... there is a shutoff valve on the fuel line... you can remove the line and open the valve.

 

It is rare in Europe, or anywhere else, for tanks to be punctured for fuel theft. The great majority of fuel theft is regular, small volume theft of say 5 gallons/25 litres at a time. This way the thief can regularly steal without being detected. The spiral spring device mentioned in this blog was avaliable in Europe about eight/ten years ago, but has been superceded by the type mentioned South Africa - with very small holes and excellent flow - and set screws to ensure it cannot be levered out. There are US models available.

 

That is many times done by company drivers, especially in GB, that's why anti-siphon devices are very popular there. They use the fuel in their own cars.

In truckstops around Europe tanks are always sucked dry, like happened to my friend last week in France, he was parked next to some truck from Lithuania that was not there when he woke up. Tanks are not punctured at truckstops but at some more quiet places like industrial areas when truck is left alone.(and you have an anti-siphon device)

 

The comment about punctured tank in Europe states a rare occurence. Anti siphons are used extensively in Europe. DAF (Paccar) and Scania supply many across the continent and majority are to repeat customers.

The spiral spring type disappeared five years ago and were superceded by the type the South African guy mentioned.

 

My anti-siphon device is to just keep the truck rolling hard to steal from a moving truck

 

I am a mechanic and have seen a few fuel theft problems, from steeling just a few gallons, to removing the plugs and draining the tank, drilling a hole in the top and the best one was a group that had a vacuum truck set up with three hoses, they just put this rubber cup on the tank and sucked it up to seal it then with a cordless drill drilled a hole in the bottom of the tank tank the hole saw was captive in the rubber plug. If there is a will there is a way. We had a customer that put in an anti siphoning devise, and it slowed down his fill-up time so much he took a bar and drove it into his tank he turned it around and got it up enough to pull it out.
