Ok those of you running OBA or ARB's.....

Any of you put in hard lines (tubing) then to adaptors or flex line to the ARB's. What did you do and where did you get the parts? Pictures would be cool.

I ran aluminum tube to the back with compression fittings on both ends. Standard ARB plastic tube down to the diff. I don't remember exactly what I used for adapters, I just went to Orchard Supply & found fittings that would work.
As far as I can recall:
1) I used a std. 3/16" compression fitting with a metric (5mm ?) crush sleeve to adapt to the blue hose.
2) The threads on a 3/16" comp. fitting fit the ARB actuation solonoid, but I had to use a rubber washer to get it to seal.

I used 1/4" Stainless steel .035 wall tubing. I used this because it is hard and durable and looks nice once its bent. I got it from Modesto Windustrial, but you should be able to get it anywhere that supplies this stuff. I paid right under a buck a foot for it. I used the stainless braided hose with teflon inner with 37 degree JIC type connectors for the flex tubing. I got it from McMaster-Carr.
