Hi Slickmouse,YES that's a BIG NOOOOO You should also line your gas cuboard in metal with plenty of holes in the bottom,gas being heavier than air so if you have any leaks it vents out of the bottom
Not questioning your ability but are you sure you should be messing with the gas bits ??? or was it a lpse of memory asking such a question :thumb:oh:
Any pics of your build so far?
Some of us have large LPG tanks mounted on their side under the motorhome, but these are special vapour draw-off models. Other than the take-off pipe drawing from the vapour space at the top instead of liquid at the bottom (you need to look inside to see the difference), they look identical from the outside and the filling procedure is the same as those fitted to LPG-powered cars.
If you go to www.lpga.gov.uk and find a autogas fitter close to you and ask them they should tell you all about vapour tanks, alternativley find cargas in Stoke on trent I personnaly know these guys and know they have fitted lpg system for motorhome habitaton
