sorry for the dumb NOOB question

[sil*eighty]

Hey guys, real noob question here... and dont think i havent looked... i know the wrath of my fellow zilvians enough not to try and search before i ask a stupid ass question..

but heres my q.
what in the fuck is this line called?.. * i was thinking oil return... or something i dont know*






and since i have an aftermarket tubular mani and that stock oil / air separator was taken off.. i have this ugly piece of shit cut in two pieces and held together with zipties and heat tape oil line from that T fitting to the engine and im sick of it.. i want it replaced... but im thinking because i dont have that air/oil separator if i were to get the stock lines that wouldnt help me at all...so what do i do for a line?. what are some things that you guys have done.. *i know steel braided lines and w.e. but im talking about sizes and possibly websites so we can be on the exact same page* also post pictures if you have them of what you did for that line.
i know im asking alot but fuck me it looks like shit.


thanks guys sorry again for the nub Q.

Let the flaming begin.
