I would seriously suggest you have a Licensed Gas Fitter look at it. Apart from the fact that it is illegal for anyone but a Licensed Gas Fitter to work on the installation, there is the danger of gas leakage which can result in fire or leaking into the Van causing death. Just not worth it.

Since light travels faster than sound, some people appear bright until you hear them speak.
I have recently changed the regulator and the tap - makes a huge difference. Can buy them at a hardware shop. Some come with copper pipe as well but too short for the van.
