Anyone have some in date CNG cylinders knocking about? No I don't mean the aerosol cans you all use for LPG, CNG runs a 'proper' pressure. 200-250Bar. You'll know if you have a CNG cylinder, it'll look more like a welding-cylinder and be at least as heavy. If you tried even 100Bar in your LPG tank you'd have a bomb. I'm always on the lookout for these so if this post appears old by the time you see it, don't worry. I still will want them.
Don't be surprised if I want the car they came from too.
