I've been collecting parts to upgrade the turbo on my AHU to a VNT-17 and ended up with a question about the feed line. I purchased an aftermarket, braided feed line and realized that the end of it has an o-ring in a groove that was cut into the fitting. This seems out of place to me... I would think the fitting should seal without the o-ring, as it is the same idea as the flare on brake lines or AN fittings, for example. The aftermarket ones I find online all seem to have this o-ring; but as far as I can tell, the OEM feed lines do not. To be fair, though, I have no first hand experience taking off the feed line from an ALH. All my experience has been on a 1.8T which uses a banjo bolt and I am simply going off of second hand knowledge and diagrams. I don't see a seal shown in the part diagram.
So my questions are whether that o-ring should be there or not? If it should, is it the right size? And if so, how do I get it into the union on the turbo without slicing through the o-ring?
