So I am revamping my LS-T set up and wanted to switch my rubber oil drain line to braided. I started digging through my left overs of AN fittings and braided line and the only -10 line I have is different from the rest. It's not black rubber inside but rather a white/opaque plastic like hose.

It seems kind of thin and I'm worried it could melt. It's been in the shop for years, if memory serves me correctly I got it from a friend with a Supra as left overs from an eBay oil drain kit ..... but IDK.

So, has anyone seen or used such steel braided line for oil drain?

 

I wouldn't, that oil is damn hot and you don't want to risk adding melted plastic to your oil source.

 

Also most plastics are not oil resistant and will dissolve
