RE: 3-line fuel system
Hello,
3 line system:
You need to run three lines from the tank. 2 of them need to be attached to fuel clunks(pickups) in the tank. One of these is for fuel line to the carb and the other is for filling and de-fueling the plane. The third line is a vent line that can just hang under the cowl or out of the bottom of the plane. DO NOT CAP THE VENT LINE WHILE FLYING!! This will collapse your tank and cause the engine to die. The fill line can be placed outside the cowl with a fuel dot and capped when not in use. I hope this helps. Email me if you need clarification.
