Does anybodu what part number the teflon washer is for the high pressure hose fitting. It's the one on the pump.

I do find 389349 and 387571 as a seal in some of the power steering parts lists.  But they are also listed as an o-ring.  I don't find any mention of "Teflon" in that section of the catalog.

One section of the image Steve posted above shows a Teflon seal on the "Tube nut", but that looks like a different set-up that what the regular pumps have...



I know on mine, the tube sticks out from the end of the nut and it has an O-Ring on it. There's no Teflon seal...not on the tube nut at least (On my truck).



Mine looks like this one above, with an O-ring groove in the end of the tube. No Teflon. This isn't shown on Steve's image above. Unless Steve explains it differently.

Cory - That's been my experience as well.  But I do see some things in the catalog, which are used in some applications, like this:

*384975-S94 (KK-46-F)-"0"-ring (19/32" O.D. x 7/64" thick)

Or

387573-S (QQ—67—G)—ring

I don't know what those are.

The diagram is probably from a '92-96 service manual, but it shows what I remember about my original '83.  The C2 pump & its fitting didn't change.  The pic you posted looks like an aftermarket replacement that's a slightly-different design.

Working at the dealership, I installed a few new Teflon seals the way that shows.

Ahh, OK. That explains it then. If you look up the pressure hose for a 1994 (for example) it shows the style in your diagram above with the Teflon seal. It must have changed in 1992? The pump/hose in my 1984 and the 85 both have the O-ring seal like in my first picture above (Both Ford, and aftermarket).

Yes, that last pic Rembrandt showed is what the line looks like on his truck(1997). It doesn't have the type where the tube sticks out with the big rubber O ring.
