Does anybody have a kit for the turbo return line yet?

I'm looking for a turbo return line kit for a 6.5 turbo diesel, similar to what Raceday mechanic has for the HX.
I made something up for the 96 Suburban by combining parts and ordering more. Raceday's kit will not work on the 6.5 OEM turbo.
The part that comes off the turbo crashes and you can not get to it to easily remove it. Defeats the whole purpose of doing the upgrade.

I like the way it ended up, but I do not know my fittings or braided stainless to put something together myself.

Even just a parts list would get me there.

I've never had an OEM turbo return that didn't leak after a short while - Not to mention they are a pain when pulling the turbo.

I want something like I now have on the 96 Suburban that you can just disconnect a hose and not mess with those 2 little bolts.

This is the hose I used - 3/4" High Temp Silicone Hose

I'd like to take it a step further and use braided stainless.

I have these fitting on hand - or should I just scrap them and go with something different: http://www.ebay.com/itm/271468994889?rmvSB=true&rmvSB=true
What would I use for sealant - apart from getting an aluminum nipple and welding it in?

Would regular pipe dope hold up right here with the heat from the turbo? Especially on aluminum?

I am not sure what will seal the threads since it is starting off with a female and will not be funneled into the next fitting. The last time I had the tig welder out I was a disaster.
With as many certs as I have had, I'm embarrassed to ask a friend to weld something for me.

Looks like we will have 6.5's for the foreseeable future. I want things the way I want them as I go.

For my ATT original I brazed up a piece of copper tubing to the factory flange and ran down to the blocks coupling tubing, for 2nd ATT I cut the original steel factory steel line, in the middle just below the exhaust manifold for heat reduction purposes and used a piece of heater hose as a coupling, so far so good since 1st installation in 2008.
