CNG was called SAFGAS by the people who marketed it. It was because a leak was considered safe since it is lighter than air and floats away instead of settling in the bilge as a flammable pocket of gas like propane leaks do.
This is the first sloop I owned and didn’t just crew on. At first I think it felt like cheating - sailing on the jib alone, but it works so well when the wind is 12 or more that I’ve come to accept it as the way to single hand my boat. Which is what I do 95 percent of the sailing season.
While I am certainly no expert, I suggest taking the filter off (it is the RACOR filter right?) dumping it, and filling it with diesel. Also did you change the filter at the engine too? MAke sure the racor is on tight, a little intermittent air leak will drive you crazy.
Hi Vikings! - This is not an argument, I know a propane system is in my future eventually, but I was able to fill my CNG tank from 0 - 2200 psi for $1.40 at an EXXON self-serve station in King of Prussia PA. this morning. As long as I can do that I will.
