Drill a hole smaller than the tubing in the cap. I have found that a 11/64th hole works great with the normal green silicone tubing. Then cut the tubing at an angle. Thread the end of the tubing into the hole and pull it the rest of the way through with pliers. It should be VERY HARD to pull though. If you have drilled the hole the right size you will have a gas tight fit.
