The renix engine has a different fuel set up then the high output. I have a steel line that connects in to the fuel pressure regulator and on the other side of the steel line is a rubber line(sends gas from the fuel tank to the fuel rail) then there is a rubber line that is going back to the tank(it has a metal fitting crimped to it to snap on to the fuel rail. The plastic clips disconnect when you squeeze the two ends and then it releases. What I'm missing is a plastic spacer that is between the quick disconnect clip and o-rings. it goes quick clip, o-ring, plastic spacer, and o-ring
