I'm pretty sure my RV's original P/S pump is leaking from the pump's seals itself, not the pressure hose/o-ring, which I replaced last year. I mean I could be wrong, I'm not really sure. Is that the typical seal to fail on the Saginaw pumps?

It's so hard to tell where it's coming from. It looks like it might be coming from the pulley shaft side though, since it looks damp on the lower side the P/S pump, below the driveshaft.
Then again, the steering gearbox has fluid dripping from it too by the pitman arm, but not up top where the hose connections are so I don't think it's the hose connections. Maybe the gearbox is leaking and the fan is blowing it back to the bottom edge of the pump? seems like the front of the pulley would be damp in that case though.
The leak has gotten much worse lately, to the point that I have to refill it after 100 miles or less, because the pump starts getting noisy when tuning the steering wheel at a stop from lack of fluid. (It could be when driving but impossible to hear)
