rqsall Posted July 17, 2012 Share Posted July 17, 2012 Hello, I replaced the power steering pump on my 1991 RR (3.9 EFI). It is the one with the big nut on the side. However, now it leaks at the fitting where the pressure hose is connected to this big nut. Looking at the parts catalog I see an O-ring roughly where that hose would be. The part number is RTC4826. Looking at the old PAS pump I do not see a seal in there, but it may have fallen out when I was replacing it. The hose is also flanged, like a brake pipe, so I'm in doubt if there should be a O-ring there. I've removed the big nut thingy from the old pump and there is an O-ring where that big nut enters the pump, is this the O-ring the parts catalog shows? Or should I really put a seal on the flanged pipe. Thank you for any answers Quote Link to comment Share on other sites More sharing options...
