making a Co2 siphon tank

[Drcemento]

rebuilt a few tanks with anti siphon tubes... now i have a glorious 68 special build about to be competed and I need to take one of my old tanks and make it a siphon.

been using 1/4 NPT - 1/8" compression fitting with 1/8" flexible copper tube for my anti siphons - assuming I use longer tube pointed to the lower rear of tank and make the tank specific to the gun.....but

I recently saw a buddy's 68 special that had the OG siphon tank with it and you could hear the tube clanging around like it had a weight on it and would always be a dip tube regardless of the gun

so - experts - anyone know what they used to do that or have advice for making up a siphon tank in general?

There should be a guide from doc on this. I believe he used microline with a fitting on the end as a weight.

Thats the ticket! that thread did not show up when I searched for some reason

looks like macroline is the key. anyone have a good source for 1/8" macroline - much harder to come by for some reason
also is there a prefered compressio fitting for use with macroline - the yor-loks on mcmaster have 2 part sleaves.
