The Brake Caliper Nipple is 3/8" UNF and the Oil Pressure take off I think is a Tapered Pipe Thread....

The hole in block is 1/8 BSP, parallel thread. The oil pressure switch male thread though is tapered, [edit] it's 1/8 BSPT

NOOOOOO
that is a Yankee thread, a bit bigger dia. A 1/8 NPT switch nearly fits... but you can run a 1/8 BSPT die down it, then it's right.

Ya want a 1/8 BSPT one. :wink:
Briddish Standard Pipe, Tapered.
