Braided Oil feed question

[umpkin]

im gonna make a replacement oil feed for my mk1 engine, i have asked this before, but was never really cleared up, do these oil lines have a restrictor??

this kits shows a 1.5mm hole in the feed banjo bolt, is this right?? or do i not need to worry about this on the long mk1 pipe???

i really need to clear this up, as i dont want to spend a load of money on a refubed turbo, and then over oil it etc.

or give me a number of someone that may be able to help.

Cheers guys.
