Komatsu D20P-5 injection oil line leak

[Colby Macomber]

Hey all,
I recently acquired a komatsu D20P-5 with the 4d94 -2n engine. The dozer had been sitting since approx. 2007. After getting it started, it started to leak oil from what looks to be a fitting attaches into the block to a oil return line for the injection pump, I have been searching the internet, forums, and diagrams trying to Identify/ locate a replacement part with no luck. I have attached some picture of the issue part. If anyone has any insight into what it/ how it is in the block (threaded or press fit), and or where I could locate a replacement it would be much appreciated. Or if anyone has one on hand that they don't want to part with and would be willing to shoot me some pictures and dimensions would be fantastic as well. It looks like I should be able make the part or at least something compatible if I have to, I just want to get as much info as I can before I resort to that.
Thanks
