I searched and could not find the info I was looking for. My stock line cracked so I decided to use the extreme PSI OFH oil line 20G kit I had, all I needed was the -4 fitting for the FP T28.
I took my extra blown FP T28 to my local shop and we tested fittings tell we found the right one.
XRP 402804 -4 male to 7/16 -24 male inverted flare.
It came with 2 and that was a good thing. Running the stock oil drain and the extreme PSI OFH 90*, -4 line and the XRP fitting was TOO much oil pressure. Puffs of blue smoke would come out when I got into it and just reved it. Here where the 2nd fitting comes in, the stock OFH fitting/restrictor that goes to the ¼ oil line is the same thread. So I used the 2 XRP fittings and just the SS braided line from extreme PSI. No more blue smoke, no oil leaks.
