Jeff,
I did notice the oil pump outlet connection location in the photos. Unless the passage in the front iron going to the front cover O-ring has been plugged, capping the original front cover port still leaves the O-ring subject to the oil pump outlet pressure.
I used the same front iron oil pump outlet location that you are using. That location is connected to an FC598-10 Aeroquip Socketless AQP hose which is the same type of hose that failed for you. Did the hose itself fail or was the failure at the connection?
While the oil pressure and temperature in the hose are well within the specs for the hose I am using, your experience has me reconsidering that decision. Maybe the specs refer to the hose itself and not the actual connection?

Steve, one thing I forgot to mention: Due to the potential of front-cover, o-ring failure I elected to not use that port and capped it. I removed a brass plug from
the front iron and tapped that port to accept a 16mm to flared AN fitting – that is where oil comes out of my engine. If you look carefully at the last two photos posted you can see it.
