Turbo Oil Feed line - PTE 6466

[seeblackrain]

Hi, I am looking to replace a leaking 4AN turbo oil feed line that's going to my precision 6466 turbo. The original one from big boost leaked on me horribly. I replaced it with something in a pinch, and it's been about 8 months and I'm slowly seeing some sweating around the fitting.

I need a 4AN 90 degree, and about 24'' in length. I found this one, but there is a certain size restrictor inside the fitting. I've seen K-Tuned makes a quality line, but no mention of the restrictor inside.

My question: What specific restrictor size should I be aiming for? I've reached out to Big Boost and Precision without a response.

I thought the restrictor is already installed in all precision turbos and an external one is not required?

That was my assumption up until I am seeing this AN lines being sold with restrictors.

My 6466 already had it installed its a 9/16th fitting that I attached my oil feed line to. The feed line had no restrictions in it.
