Ok I have two O.S. 46 fx's and here is how I have my fuel system set up...I have a 24 oz fuel tank, I have two clunks in the tank with two pick-up lines, one going to the left engine and one going to the right engine. I only have one preasure line leaving the tank and then have a T splitter with one line going left and the other right. I have this problem when I am only running one engine, the opposite engine starts to get flooded with fuel. I am guessing the preasure from the operating engine is pushing fuel to the dead engine?? If anyone knows what I could do to prevent this please let me know! Thanks so much!
