Default Plumbing ??

I have aquired a twin engine stick type plane with a pair of ST .29's on it they have the tanks mounted behind them and muffler on the engines, they also have a perry pump for each engine. The pump has a line from the engine crankcase to the pump and then the line from the tank to the pump, and from pump to Carb. there is also a line from the tank to the outside and not attached to anything... Someone explain this plumbing to me...

Thanks Don//

You just explained it to us. What more is there to say.
[*]The line from the crankcase to the pump is a pressure impulse line that runs the pump.
[*]The pump draws fuel from the tank and delivers it to the carb.
[*]The tank is vented to the atmosphere with the line that doesn't connect to anything.
[*]To fill the tank, disconnect the line on the pump that comes from the tank. Refill your tank through this line then reconnect.[ul]
