correct hookup for pressurized fuel tank

Hi Guys,
What is the correct hookup on the cap of a pressurized fuel tank? I know the line in tank with clunker goes to carb. But... does the vent line in the tank with curves up into the bubble of the tank hook up to the muffler pressure valve? When the tank is full won't this push fuel into the muffler? Are these the only two lines needed going into the fuel tank cap?

Yes it will push fuel into muffler. Tells you the tank is full!
You can go as described or have a third line for fueling which needs to be plugged except for refueling.

You just disconnect it when you fuel, so it does not fill the muffler.

Or you can leave the pressure line hooked up while you fill PROVIDED that it the muffler is below the cylinder/head (I.E. horizontal or inverted mounted engine) and pointed down. When fuel drools out, tanks full!
