Cappaj1,
You don't necessarily have to remove the muffler line to fill the tank. If the muffler is pointing down you can pump in fuel and when the tank is full the excess will flow out the muffler. It's very important that you do this on a muffler that points downward, otherwise the muffler will fill up with fuel.
For a three line system you need something to close the third fill line. Either a stopper or a fuel dot. On the B-25 review I just finished I used the stoppers that you listed above. Look at the review and you can see how I dealt with them. [link]http://www.rcuniverse.com/magazine/article_display.cfm?article_id=1011[/link] . Presonally, I prefer the fuel dots. They are quick and easy to set up, and foolproof to use.

Thank you!
I skimmed the article - really nice build and article by the way - to the section on the three line system. Two more questions:
1) On the OS Max 46AX muffler the exhaust outlet is facing down but the connection for the tank line is on top. Is this okay?
2) Am I on track with about what I'd need below?
Stopper with three holes, three bendable lines, two clunks, fuel line, two cowl mounted threaded fuel dots (
