A while ago Gene and I put in a propane injection system that puts in a small
amount of propane into the engine that does a few things. First it allows a
higher octane to go in and helps when climbing hills, secondly, propane is
supposed to keep the carbon from building up in the engine, so a small amount
goes in all the time....but the most important part of the system has nothing
to do with the engine. It requires the installation of a special valve as the
first thing from the propane tank. It was developed for earthquakes and other
catastrophic events. In the event that propane goes through the line at a
higher pressure (i.e. if the line breaks) the valve cuts off all propane to the
coach. I find that this satisfies my safety concerns about leaving the propane
of when I travel.
