Cat, could it be that I have 3 oil pressure sensors, well I do. Could not see the third sender I have all the books and it only shows 2 sender and I replaced the one I thought went to the ECM. I went to Peterson on Monday and showed the same guy that I worked with on my oil pump, about 2hrs of his time and I showed him the sender I changed and he said that is not a Cat sender
So he got on the PC and gave me all the info I needed, O rings and sender so I installed everything today, ran for about 1 hour so far it looks good. Will take it on a run in the morning, about 50 miles. I think it will be OK.
Thanks for the help on the oil pump Cat and the info on my motor.
