Garrett oil and water feed lines

[jdmser]

What fittings did you use to plumb your Garrett. I have found a few different combination what would work, but want some opinions. The oil drain tube fits so I'm using it. I got a -4an flange for the oil feed with a built in 1.62mm restrictor. So, what I need are the water lines and the oil feed line. As always any thoughts are appreciated.
