how can i secure my airline through the cap of my 2 liter bottle. i do not want to have to order those bulkhead fittings and i have tryed epoxy but can' get a good seal.
does anyone have any other suggestions of what i can use that i can get locally?

thanks,
Wes

Get two new(undrilled) bottle caps. Drill your holes much smaller than the tubes, then using pliers and elbow grease, pull the tubes through the holes. Makes a very tight seal. Before I went pressurized I used that for 6 months and never had a leak.

I agree with jmhart. The first few I made I drilled 1/4" holes for 1/4 hose and then used globs of silicone. I recently tried the smaller hole techniquie and have a diy bottle on a new tank I just set up running no problem without a drop of silicone. In a nutshell, if you are using 1/4 airline, drill a 3/16 hole. Cut the end of the hose on an angle so you can poke it into hte hole, then pull it through with pliers. If I can find the link with more details and pictures I'll post it for you
