Turbo oil feed and drain -AN hose/fitting sizes

[SteveH]

What size -AN fittings have people used when replacing the OE turbo oil lines?

I recon the ID of the oil feed pipe is 10mm and the drain must be 19mm. I've read a few posts and I'm not 100% sure whether the -AN number is the OD of the pipe or ID

I'm after some weld-on fittings to use the original flanges but want to make sure I get a size that's not going to restrict flow in or out.

On my precision turbo it's an4 feed and an10 drain .

Thanks. I'm still using a kkk, but that gives me an indication of the size of the return hose into the block.

I would use a -12 or -16

The bigger the better on the drain, I'm using -12
I don't think you can over supply oil to a journal bearing turbo, -4 seems the norm but you could go -6 to be the same as OEM

Cheers! Ordered my fittings and just need some decent braided hose to make up the pipes.
