Re:Saab T3 Supply Oil Fitting
 

I've actually seen a few t3's like this with no threads on the feed side, they normally have flanges on them with hard lines. Easy fix.. just get a 1/8th Tap, and tap the bitch out, just besure to blow lots of brake/carb cleaner through the centersection housing, and blow it out with air to get all the shavings out. (I like to put greese on my taps so it collects most the shavings.

good luck,
