By the way, I went to buy more P/S fluid...the Manual calls for Type A fluid.
The auto parts store stocked three separate brands...none were called Type A.
One was for "pre-80's Mopars", but I went with a different brand, which the counterman thought would work fine.

Roger - I used the inexpensive (cheap) o-ring and haven't had a problem since, but I will keep the Hi temp silicone o-ring in mind, at $8.00 its less than a whole kit. Thanks for the tip.

I have no idea what my $1.00 "O" ring is made of but I have had no problem with it yet. I've been using trany fluid in my power steering since day one. No problems. I still haven't replaced my heater hose pwr steering return line yet either. One of these days.......

The answer was in the literature.
The Supplement p 78 does not specify the p/s fluid, other than Type A.
But I went back to the 57-8 Service manual, and on p. 496, it tells me to use Type "A" TRANSMISSION FLUID.
and of course now I remember that I have been running tranny fluid in there.
Hey, it's an age-thing. Only I am getting old too fast!

I put it all back together today. While re-installing teh return (large diameter) line onto the pump, I realised that due to age, the hose had flared and the clamp really wasn't doing a good job of sealing.
I sawed off one inch of the hose and re-installed the hose. Refilled the reservoir, started the car, trurned the wheel fuuly left, then fully right.
The skies cleared finally (6 pm), so I took her out for a short drive. Runs pretty good.
I had noticed a few days ago that one spark plug wire had fallen off the distributor. (Isnt a V-8 great?) I would like to get a little more immediate repsonse from the accelerator pedal,...maybe it is a timing issue.

Well, did it leak or not??????????????????????

I topped of the reservoir after the test drive.
I will check the garage floor for telltale signs tonight, Dick!

Roger, Type-A fluid was superceded by Type-A, suffix-A fluid in the early sixties, which was later superceded by Dexron, Dexron II, and finally Mercon. These are all acceptable for use in our Mopars.

Excellent! Thank you very much for that bit of info. I think now there was Mercon IV in there, plus a bunch of anti-leak stuff. I filled what was lost by part removal and cleaning, with Mercon V.

Although I can't say for sure whether the leak was coming from the "O" ring or ( ) the low-pressure hose connection, it doesn't seem to leak now...

Success!

A job well done!
