I've got myself some tidy hose clips ( the same ones the battery cable is going through) for the hose pipe.
A couple of battery's .. the big chuncky ones ( not sure what the size is called)
UK low pressure regulator
A sticker to say your carrying LPG Gas..
I'm going to fit a fire extinguisher too -

Its such an easy set up.....

Just make sure your Di 'Out' goes to the Heater ' In'.... and you can't really go wrong.
