Default Oil inlet on turbo leaking

I've got a Turbonetics 7875 bb turbo that is leaking oil from supplied fitting from turbonetics, 1/8"npt. I have a -4 feed line going into with a -10 return. It's leaking at idle and cruising around. I've tried tightening the fitting, but it's damn tight as it is. Any suggestions?

Where is leaking, from the NPT case to fitting, or fitting to 4an feed line?

It's leaking on the case to fitting. No tape was used since it was already installed from Turbonetics. I used tape on the -4 fitting going into the fitting.

Yes, pull it and add tape/paste.

The 4an should be a face seal vs the NPT and I would use paste sparingly.

Yes sir. Has a screen in it. Got some tape on it and all is good right now at idle. Going to take it for a drive tomorrow and see how it does.
