Joe, you are correct about the test pressure. Actually, it is 3psi as stated by USCG, and I have a modern Tempo plastic tank that has the test pressure stated as being 3psi. Those pressures are used for testing leaks. But, that is not what I’m looking for and so far, even after talking to retired OMC engineers, there’s no answer to my question.
If you were to go to court to prove a point, there would have to be confirmed documentation to support your argument. So far, I don’t have that documentation that says a tank is safe up to a specified (documented) pressure. So for me to say there is a safety factor of, let’s say for example, 3 to 1, with the vent pressure being 7-8psi, the rated working pressure of the tank would have to be 24psi (3 x’s 8psi).
If we, as the Pioneering Authority, write articles, I’d like to know from my personal standing, that what I write is defendable..
You folks are the best, and I appreciate all the wonderful comments and the fact that you all are interested!
