Xc90 power steering oring
 

My 2012 d5 xc90 has developed a power steering leak.

The high pressure line out of the pump was leaking so I took it out and found the "Green" oring was leaking.

Ive a generic box of orings but none the same size- seems to be between the sizes I have.

So anyone got a part number for this oring so I can check online for one?

Thanks.
