LPG system

Hi group, I'm having some issues with my now, old, LPG system. I suspect it could be leaking gas into the cooling system and possibly creating too much pressure in it. Has anyone pulled apart / repaired an LPG converter, and is it possible for the gas to enter the cooling system via the converter? The converter has been leaking a little coolant lately so seals could be on the way out. Thanks for any advice , Eddie.
