I am just starting to plumb in the oil pressure gauge on my J4 restoration. I don't have any of the plumbing that was taken off before I got hold of the project. Can anyone tell me what the correct fitting is on the crankcase. I am struggling to identify a pipe end fitting that will connect to the one on the crankcase. I am not convinced that it is original.
I also understand that there should be a restrictor somewhere.
