Power Steering Pump O-Ring

[truckster]

I'm installing my Redhead steering gear this weekend. I have a leak from the PS pump that I want to fix at the same time. It's leaking from the adapter (the adapter that goes into the pump housing) and I suspect the O-ring in there is the source of the leak. It's not the O-ring to the hose (I'm using flare fittings). I can't find a size for the O-ring and I want to make sure I have on on hand when I take it apart. Anyone out there know the size?

You'll need to remove the pressure regulator (it's not an adaptor) and reservoir to gain access to that O ring. There's a spring and other parts in there, don't loose them. O-rings are not reuseable, so you'll need more than just that 1 O-ring.. Do yourself a favor and don't order blindly online.. GM used the same P/S pump on various models for years, so the exact year model isn't necessary.. O'Reillys has the O-ring kit in stock.. The kit is also available from various other local parts suppliers.

Here's a link to that kit.
