Hi Everyone I have a fuel flooding problem Here is the problem. I have recently got a Bell47g and the tanks on the side were cut open and 2 sullavian tanks placed inside of them the fuel flow from one tank to another works fine the problem is the tank that feeds the engine keeps flooding the engine I have to turn the needle valve all the way in shut the fuel flow off or it will flood the engine . Now I know since the tanks are higher that the engine it seems its acting like a siphone even with the engine off if you pull the fuel line the fuel just keeps coming out how can I solve this problem .
