Hi, I have a 1997 Legacy wagon that had a leaky power steering pump. I replaced the seals with a gates 348414 kit and now the pump is dry. Now, unfortunately, the pump is no longer working. I did notice that the small internal o-ring (the one in the same area as the large o-ring) seemed a little big when I put it in. Could that be the problem? The pump is not making any noise and the car is running fine otherwise. It seems that the power steering fluid isn't circulating. Any ideas? Thanks.
