Camping

[Phil]

To fill it I have a length of small flex tube and a small syringe, like you get for filling printer ink cartridges, to get a siphon going. 

I bought a 1m length of 6mm tubing from B&Q. Put most of it into the tank, put your finger over the end, then take most of it out and when the end with petrol in the tube is below tank level you are ready to stick it into the stove and it will start siphoning. I think I will get an interim container and siphon into that first. Petrol is a bit smelly though.
I had a failure with a gas canister seal once. Having a 1/4 of a can of gas escaping out was a bit scary, it was a good job the stove wasn't hot.
