Looking for info oh what is involved in replacing the brass seat that the flared tube seals against. I'm finding brass Inverted Flare to O-Ring adapters but something tells me the ones used in Saginaw boxes are pressed in. The picture is just a random pic from the interweb.1671842538869.png
 
Since you already have your steering box out basstrix it's easy to replace the Brass inserts. But an effective easy alternative with the steering box installed are copper cone washers. Especially with the tight confines in that area

Been there, done that.
As you already have the schematic, no point me posting that now. What you do need to be very careful about is the check valve in the HP port. It MUST be put in correctly with the spring. Buy new is my recommendation.
When I did mine, I had an issue getting the correct flares for the 800 box. Even then, I found that the ones I bought (from Green Sales) were too big to be pressed in. I needed to turn them on a lathe and if I remember, it was 1 degree taper. I only took off maybe 3-4 thou. It's been about 5 years since I did mine. Then I had to make up a tool to press them in. If they are too loose, especially on the HP side, they might leak backwards causing seepage from the threads. That is the way I saw it anyway.
SEE PDF.

I did exactly that with the pressure line at the power steering pump. Works great!
 
On this subject. I recently upgraded to the Borgesian power steering box, my installer used my original hoses and I have a leak at the fitting on the return side! Should I swap out the lines using the new ones in the kit or might there be another issue? Thanks

If you paid to have it installed, bring it back to him.

The box is still in the car...that was just a random picture showing the parts I was referring to. Where did you get the conical copper washers? I have an assortment of flat copper washers and I put one of them in to temporarily stop/slow the leakage, but I'd rather just replaced the damaged seat.

I saved the pdf. Good stuff. If you have the PN's for the Green Sales parts, I'd like to get that from you and see if they still have any available.

I'll see if I still have that info. I remember I had to re-order as the first set I got were NOT for the later Saginaw PS box.
Stay tuned!

I ordered cone washers thru a place called "FasParts" on Amazon. If you have a HVAC parts supplier near by they will have various sizes in stock. They are used extensively in that industry.
 
Bummer. First thing would be to tighten the line nuts to see if the leaking stops. Crows foot line wrench with an extension and ratchet make short work of a difficult to get to location. I wish I had bought this set twenty years ago.

Crowsfoot line wrenches are on my wishlist. For this job, I'm using a 12 point hand wrench. The 6 point is cumbersome due to the wider angle needed.
