Drivers side just in front of the steering box. I had just removed the bypass oil filter assembly troubleshooting low oil pressure and there it was just sitting in the frame making me think it was something I did. I doubt it would have stayed in that position while I drove the truck. I thought it went to the bypass filter holding down the internal filter but it doesn’t fit around the internal pipe.
