Technical Oil pressure sender thread?

[86Fran]

Hi, does anyone know what thread the oil pressure sender unit has on it?

I have tried searching but no luck so far.

I am trying to get a correct fitting in order to check my oil pressure with a mechanical gauge, not an electrical one.

Thanks

Fran

M14 x 1.5 parallel thread I think, some banjo bolts on fuel filter housings etc. have the same thread.
