Ford 9n Governor Oil Line Question

I am repairing a Ford 9N tractor for a friend. The fiber cam gear was worn out and I have replaced that. My question relates to the oil lines that run outside the engine. The oil line on the bottom of the filter canister makes a sharp 90 degree turn and goes into the side of the block. Does that configuration mean that the tractor originally had a cast iron governor that did not require oil going to it? The tractor now has an aluminum governor that has a oil line going to it and someone did this by removing the oil pressure gauge line from the rear of the block and installing a line from the T-fitting on the back of the block and routing this to the governor. I am thinking that this routing would most likely allow the engine oil to go to the governor and not through the oil filter as the oil pressure would take the least path of restriction. I am assuming that I should change the oil line that comes out of the bottom of the filter and fab a new line that goes over to the governor. I am assuming allot as the only information I have is in some of the parts listings for this tractor showing the little 90 degree bent oil line being available. I have looked at many ford 9N/8N's around me and none of them have the oil line coming out of the filter bottom going directly into the block.

Quoting Removed, click Modern View to see

Early model 9N's went straight back to the block from the filter. Ford saw the error of their ways fairly quickly. What you have is a farmerization that bypasses the bypass oil filter. I would think it would adversely affect oil pressure as well. To duplicate the Ford fix re-plumb what you have to go from tee on block to filter and from bottom of filter to governor and all will be well.

I have "restored" several 9Ns. I never added a governor oil line to any of them. I would just eliminate the governor oil line if it was mine.
