oil feed line doesn't fit

[WIDSM]

So I ordered the map oil feed line like the one here. However today when I removed the set screw from the ofh after cranking on it with a cheater bar I realized that the fitting I was given isn't even close to being the right size. The fitting looks like an m8 where as the plug looks more like an m10. I know I took the right plug out I just don't understand how they could ship me the wrong part or am I just missing something here? The elbow fitting that they give you is the one that goes into the turbo correct (Holset) and the straight fitting is the one that you put into the ofh? I can't see how it would work any other way.

The 90 degree fitting goes into the oil filter housing and the straight fitting goes into the turbo. The 90 degree fitting should be 3/8 to 4an. Depending what filter housing u have, most will have 2 allen key plugs in the front and u wanna take out the on the right which is the filtered oil. The straight fitting should fit unless u didnt specify what turbo u had and then they could have sent u the wrong one

Ok thank you that's what I wanted to hear. I did specify what turbo I wanted the fitting for but I guess they just put in the wrong fitting. I remember pming them about this to back when I first got it. I guess I need to find a more reliable vendor.
