Dry sump blanking cap

On the EU4 CSR 200 there is a hose between the external dry sump oil tank and the dry sump. When I rebuilt my engine I changed to an open oil system, and that hose was no longer needed and the unused hole in the sump needed to be blanked.

The problem is that it uses a very unconventional thread: MF22x2.0

After many failed attempts to find a fitting blanking cap I finally went directly to the source - Titan Motorsport, and of course they had one.

So for the record, the part number is:  A1016510200A3

For both theirs and my convenience I ordered it from Burton, who in turn got it from Titan.
