Could someone tell me how to hook-up a fuel tank to the engine, both 2 and 3 tubing installation? I'm building an Hobbico ARF and the motor I'm going to use is a Magnum 61. It's pretty close quarters to dress the fuel tubing. I'm worried about how to fill the tank. The third line seams to be the best solution, but what about the possible air leak when the fill line is plugged?

Thank,

Greg
