Thought of wiring it up but worried in case I found a postie face up one morning.
I was thinking of putting another tank and plastic fuel line with a mixture of sugar and petrol but gave up, touch wood no bother since.
I only had a couple of galls in mine but I usually fill up on the Sunday so could have been 12 galls, the police said they catch the fuel in a container, even these jokers lost quite a bit as you could smell it in the nearest drain. Hate to think what damage 10 galls would have done, that's why we got the police response we did.
