Thanks for the input...so 20oz tank...no pressure tap. will do. They send one with the muffler (pressure tap). How come?
The tap could be for smoke... Also -- you need to run the vent line up and over the tank, and then down the backside of the tank out the bottom of the fuselage. There is an old thread with pictures about running the vent line for a pumper carb that you should be able find by searching this forum...
