i stumbled on a huge pile of tri clover fittings, pipe and a lot of misc canisters and parts and stuff at my friendly neighborhood scrap yard they only take cash so i only got enough to plumb my rig. It is mostly 7/8 id and 2" couplers there is some larger diameter stuff also if some of you are interested i will go back Monday morning and buy it all maybe a few hundred pounds there has got to be enough to hard line at least a half a dozen rigs. i believe it came from coca cola there is syrup residue on some of it (and it tastes just like cherry cola l-o-l-a lola) ha!! so let me know by tomorrow if you want in on this glorious bounty
