Step 4: Boiler-3

At this stage you can cut a small section of tubing and feed it into the sight glass holes.  Clean up any remaining glue reside from the can as we will be starting the boiler housing in the next step.  You can also check the boiler for its "air-tightness" buy installing the fill plug, putting one end of the fuel tubing into the sight glass hole, plugging the other with your finger and blowing into the free end of the tubing.

You could also check for tightness by just submersing the whole assembly in a sink or bathtub and looking for bubbles. A dot or two of dish soap in the water makes them easier to see.
