Hi guys need to replace the factory oil light sensor on my blacktop for the VDO pressure sensor. Can anyone confirm the thread size. I'm lead to believe it's 1/4 npt(tapered thread)
Many thanks!

Wheres it plumbed into? There are some 1/8 npt threads on the block..

Hi coozer
It's the one just to the left of the oil filter.

1/4 NPT is correct

I plumbed mine into the 1/8npt one on the head since I thought if the pressures fine up there its going to be rock solid down below
