Issue, looking for o-Ring size for high pressure power steering hose connection to pump, VT V6

[JedVT]

I’m replacing my power steering pump this arvo and I have no ide what size O-ring you are supposed to install when replacing the old one, it’s the O-ring that sits on the high pressure hose connection to the power steering pump, thanks, I have a VT V6 series 2 executive
