I just got a YS 4stroke and planned to use a fuel dot and the LHS run only YS in his planes and told me not to do it with a YS because the higher pressure in the tank can pop it out and one of my friends showed me a neat affective way to set it up like JohnBuckner is talking about, He put 4 holes about 2 inches apart just big enough for the fuel lines and put rubber gromits like you would see on sheet metal for wires to go through then put a filter on one and the Valve that you need for YS engines on the other, Looks neat and works well.
