try a 3/16 straight thread flare fitting.

I was in a rush and drilled mine out and put in a 1/8 NPT. worked...for now.

I would guess that its a 1/8" british pipe tapered thread.

thats the same as 1/8 " american thread, but its one thread per inch difference (28tpi instead of 27tpi).

You can usually get away with putting a 1/8" male american pipe into a female british pipe thread hole, but not the other way around.

This is purely a guess!

i'm certain it is a straight thread. i just dont know which thread designation. go to hardware store and get a 3/16 -45 deg flare fitting.

let me know if it works....

:confused: what is the tread size for the oil pressure sending unit?I purchased a replacement Rover unit but it didn't tighten. I ended up getting an adapter from NAPA which was more tapered and tightened nicely. Not more leak.:thumb-up:
