I have recently gained solo status at my club on a NexStar. I am wanting to keep this plane in one piece so I decided to build a couple of SPAD's to further experiment and fly with. This way if a send them into the ground I am not picking up splinters. I wondering on the correct connections from the fuel tank to the engine. The diagrams that came with the fuel tank show a vent line and a feed line from the tank to the carb. Does the vent line connect to the muffler or do I need to install a third line? The NexStar appears to have three lines from the tank. One to the muffler, one to the carb, and then a fill line. I can not see if there is a vent line as well.

If I am correct in the muffler connection I assume that I will fill utilizing the carb line and wait until it comes out of the muffler (pressure?) line.

Also, is it typical to install a fuel filter between the tank and the carb, or is it one of those "a good idea but not required" items?

Any assistance is greatly appreciated.
