I also said that your drains aren't going to work.
Yes and two pepole saying its a issues, means should rethink this.
It also doesn't have to be an hose or fittings.
Issue with -12 an/jic, the nut to get something on to the flange off the turbo will be the problem. I wont be able to turn the nut to tighten it up, the manifold is in the way on the passenger side and cant have a lot of straight drop on the driver. This is what I see for a flange to get it below the compressor housing, so would have to come up with something else other than an/jic off the turbo.
-12 ts drain
This is the only other option I see but not how I would be getting a tube off it, so leads me back to that pipe from cummins.
1/2npt t3 drain
