I've always fancied one - do they stop when your tank if full? Is the fuel counter accurate at all? Has anyone used one over a number of years because most things when used for bio usually die within 6 months (even though it says ok for bio)?

Many thanks

Never been tempted, if you were unlucky to get a visit from hmrc why would you need to meter it out to put it in your own car when you can just pour it in.

I can see the attraction of such a device. I bought one and used it for many years. It makes things simpler. I've still got it but unlikely to use it again. The pick up pipe could do with replacing and the delivery hose is deteriorating due to the bio but its still serviceable.
On the plus side it will stop dispensing when the tank is full.
