size threads on the oil pressure switch

Redsnake2 · Jun 23, 2006

Ok guys i'm at work and I have all AN-4 stuff for free (well not free)

and I think the oil pressure switch is a 3/8 or 5/16 anybody know the diff?

The stock oil pressure sender should be 1/4" NPT (if that helps).

actually the oil sender is 3/8 npt, as well as the water temp sender in the manifold.
