Gas plumbing. I've done water plumbing with compression fittings. It can't be that much harder, no? I find references to 'gas tape' which I guess is something similar to PTFE tape, in that it's some kind of sealing tape? You get leak detector aerosols to find out if it's leaking or if you have big balls and are sure there are no major leaks you can use a lighter (eek! But I have seen it done
). I'd rather go for the aerosols As I understand it, you should fit the cylinder in a locker (ideally only accessible from the outside, but as I have rear doors I'll probably make it face the rear doors, simpler to do). It should be made of metal and airtight, with a vent in the floor. No flex fittings except from regulator to the piping. LP side should flow into a manifold with separate shutoffs to each appliance. Optionally a shutoff should be fitted next to the appliances. All piping apart from the flex hose should be secured to the bodywork. And, there has to be one (and ideally two) gas outlets under the fridge just in case it leaks.
Anything else I should consider?
. I got it up to 30ish in 4th gear (first time I'd ever driven a car, mind) and he said 'That's enough!!' and knocked it back into 3rd
