After control the house had part no 911815 so that means it's for M10x1.
It's not so easy to measure the the thread and fins out what it is (I think). Bye mistake I mounted a 1/8 NFT and it was possible to do it. So the difference is not big between the two.
Today I have found an adapter M10x1 to 1/8" NFT, so with that you can mount an 1/8 sensor

Anders,
If you look at the sender, an M10 thread will be straight like a bolt and a relatively fine thread. Yoiu can screw an M10 nut onto it to be sure. A 1/8 NPT will have a coarser thread and will be tapered rather than cylindrical.

Anders,
Mark had the right info. It is in service letter #SI 912-020R6.
Look on the BOTTOM of the oil pump housing. Pay no attention to the numbers on the front cover of the housing.
If you have #911-815 or 911-810 engraved under there, it is threaded for an M10 sensor. If it is #810-809 or 811-809, it is 1/8 NPT.
Bill.
