It was something I didn't replace the first time. When I started this thread I had no experience with the internals of a PS Pump. SOA disappointed me by selling a new $480+ pump as a "rebuild kit". I don't know for certain which internal o-ring was slowly failing. But most probably the -136 or -021. Those two are the ones that separate the high pressure side from the low pressure side. I'm leaning toward the -136 because it was brittle, flat, and hard when I replaced it. When it should be mailable, round, and soft.

Though I didn't replace the Shaft Oil Seal because I thought that an SAE size would do. I eventually found that you really need the EXACT inner diameter and outer diameter for that bastard. The width only needs to be less than or equal to 9.3 mm. I found one at P/N 20X32X8-MOS/D which looks like it would excel as a replacement. I haven't tested it.
