4.3 power steering leak at pump

[Pontiacdart]

I have a 1988 Sea Ray 200BR with an unknown serial number 4.3 mercruiser. I recently purchased the boat and discovered a power steering leak where the high pressure hose attaches to the pump. At first I tried changing the oring but the leak continued so I am not sure if the correct size was used. The old oring was green in color which leaves me to believe an AC type oring was used.

Does anyone know the correct oring size?

Could the fitting be warn on the hose or where it attaches to the pump? When I tighten the hose down I am still able to move the pressure hose around easily at the back of the pump.

Thanks for any help.
