Ok, I am trying to get this straight, please help. Will a NPT thread pattern screw into the Oil sending unit or do I need metric. In other words I have 2 NPT straight unions, 1 for the block and one for my feed line. What else do I need?

 

I have a kit if you'd like to make it easier on you.

otherwise, you'll need a 3 way "T" 1 side has to be 1.8 bpst male and the other 2 sides are 1/8 npt females
