If you're talking about the braided oil hose and accessories that came with the kit, neither a -3AN or a -4AN will work. The fittings on that hose are metric. The discussion about it being close to -4AN refers to the inner diameter of the hose, but this doesn't make the crimped ends on it compatable with a -AN fitting.
To the best of my knowledge, nobody has ever found a source for fittings that are comapatable with that hose, at least in the US anyway. You may simply have to replace the entire oil feed line. This was covered in a recent thread, where I gave you two links to follow. Basically, you buy the following:
M10x1.5 fitting (at block)
M10x1.5 to -(x)AN adaptor
-(x)AN hose end, hose, and another hose end
-(x)AN elbow (optional)
-(x)AN to M10x1.25 fitting (banjo preferred) for input to turbo
Where (x) is either 3 or 4, depending on your whim and the avaliability of parts.
