I bought an oil feed line off a memeber a while back. I'm ready to order the fittings for the turbo and what not but it was never specified whether the line was 3an or 4. Obviously, I've tried to contact the seller but that didn't take me very far. Is there any trick of the trade to differentiate the two? And no there are no local speed shops around me besides Begi a couple hours away that I would be able to find out. Thanks!

AN is the measure of the inside diameter of the fitting in 1/16 inch increments. So a 3AN is 3/16 ID, 4AN is 4/16 ID, 16AN is 16/16=1" ID, etc. If you got a caliper, measure it. Might can eyeball with a rule.

I bet its 4AN, 3AN is pretty hard to come across.

Patsmx5 gave the best easy check for this... Good luck.

I'll probably go ahead and order 4an since that seems to be the most common.

lol it can be done, somehow Slos13 had 3-AN braided line and he must have realized that it is impossible to find 3-AN fittings, so he unloaded it off on me

I would check it prior to ordering... Then again that is just me.

I have a -3AN feed line. Fittings are difficult but not impossible to find. It's worth it IMO for the reduction in feed pressure issues.
