Hey all , I'm trying to find out what size O-ring goes on the high pressure fitting on the power steering pump. The correct O-ring is only sold with a new pump. Any ideas guys??

I can't answer your question but I did have an issue with not knowing an oring size. I grabbed one of those plastic assortments of orings and test fit a couple and found one that worked. Since then, I have actually found use for several more over the past couple years. Just needed one the other day for an old Senco framing nailer and lo and behold I had it in that kit. Kids will probably toss the rest someday when I'm gone but that's my story and I'm stickin to it.

I don't know if this will help. I think the correct number is 15 35055. But here's a link for how to measure O rings
