My carver trumatic sbt1800 gas fire & refrigerator in my 'lunar meteorite '94' isn't working so upon removing the fire on inspection both gas pipes underneath were completely perished (1 into the fire & one heading towards the back of the van refrigerator I think?) I can't seem to find what pipes I need to replace the coroded pipes for it online after trawling the web. The one going into the underneath of the fire is a lot smaller than the other which is like a brake pipe size. Any help will be much appreciated thanks
