My gas leak happens when the tank is filled and the leak is back where the tank is. In my searches I read that the CC can be the problem if it is clogged. My rig has over 287K and the hoses to the CC look like if I touch them they will crumble. My question is, Do I need to completely remove the CC to clean it out? If I do, I'll want to have all new hoses to replace the ones that are on there now.
