its perfectly fine to use AN. My 98mm setup uses -4 feed and -12 drain.

you need at least a -10 return line with a nice smooth downward transition to the pan

-3 or -4 will work fine for a feed line thats just presure feed. The return has to be at least -10. You want to get that hot oil out as fast a possible and the straighter the better. I would only use teflon ss line for the feed line and you can your the regular rubber ss line for the drain.

What fitting are you using for the return? An AN barb? I dont want to steal the thread but I want to run -10AN return to oil pan just dont know which fitting to tap with so theres no leakage.

I've been told after getting my turbo rebuilt that the 3an line was too small for even my 76mm.
