OK I now have another issue - arghhhhh - I noticed that I have developed a leak at the union on top of the p/s pump. I went to the local automotive shop and all the orings they have are way to fat to fit. Does this part have to be ordered from toyota? and if so does anybody have the part number?

Ok since I didnt get any help on this I did some research, ordered what I found out and no more leaks.
I thought I should share this to save someone else some time.
The part number for P/S suction union o-ring on the 1jz is 90301-11016
Thats the good news - the bad news is the damn thing is 6 bucks.
