Turbo oil return...suggestions please

Hi guys,

I've been returning the turbo oil to the sump via the sump plate with no issues at all for the last year other than a small leak.
The sump plate was modified to have an AN-8 connection and there has always been a small leak from this point. After several attempts to seal the threads using 3M thread sealer I started to suspect the welds around the AN-8 fitting.

I'm at the point where I either remove the sump plate and get it redone or I find an alternative.

I was originally going to return back to the oil tank but after several attempts and different methods gave up.
I've just thought of a possible simple solution and wanted to get some input from people in the know.

Current setup :

I have seen someone put a 90degree AN fitting on the sump plate drain plug fitting and return that way but it appears to hang down a way and I'd be concerned it may get knocked.

So I was thinking that as the 930 returned oil back to the tank with a dedicated fitting low down on the oil tank I could use a M22 x1.5 to AN-8 fitting on the oil tank drain plug fitting , then use an AN-8 90degree fitting.
I'm using a Turbowerz pump to scavenge the oil. If need be I could use a check valve to stop oil draining from the tank back to the turbo catch can and as the magnetic drain plug would not be used I could install a Turbowerx inline oil filter that also has a magnetic ring to remove metal particles.

Exa-Pure™ 100 Filtration System

So what does everyone think, any advantages or disadvantages in neither way?
