A mechanic friend just replaced my power steering pump. The thing is now
purring like a kitten, as opposed to the banshee wailing it was doing. The
problem? The stupid rubber O-ring supplied for the high pressure line kept
cacking up (well, that O-ring and all the extras my friend tried from his
kits...I know they're a one-shot deal). Now my car is out of commission for
at least 2 days while he tools around the city (I'm in Toronto) trying to
find a tapered neoprene ring like the original. (This happened to him
before, he's a Mopar man but condescends to work on the "Fords of friends").
He couldn't find any at his usual suppliers. So, my questions to you are:
a) is it possible to buy neoprene kits
b) if not, does anyone know where I can buy a single?
c) does anyone know who manufactures said tapered neoprene gaskets.
Apparently the dealership's solution is to buy a new line...does anyone else
find this ludicrous? Paying $100-150 for a part I don't need just so I can
get the attached 5 cent piece of plastic?
Thanks for any answers to the above questions!

Your mechanic friend did not look very hard at the o ring. It's not rubber. No
wander he failed so many times trying to get it to not leak! It's nylon and is
readily available at Ford dealerships as well as reputable parts stores like
Would that be the original gasket you are talking about, or the replacement
supplied by Fenco with the pump.
I only saw what he was fitting and it sure looked like a rubber o-ring to me
(and I'm a scuba diver, so I've seen plenty).

Why else would o ring after o ring fail? Either it is the wrong size, wrong type
or some one does not know how to install one ( over tightening for example ) .
The correct o ring is a white nylon square cut. A round rubber can be used, but
it has to be the correct size. The correct size and type would be one used in
hydraulic straight thread o ring sealed fittings not the generic o rings found
in automotive o ring kits.

Another trick is to slide them down the shaft of a large tapered
"driver" to expand them (right after you take them out of the hot
water) as long as you don't get carried away. There is also a tool
that is made to go over the end of the fitting to make it easier to
slide it past the "bump".

"What, sir, is the use of militia? It is to prevent the
establishment of a standing army, the bane of liberty. . .
Whenever Government means to invade the rights and liberties of
the people, they always attempt to destroy the militia, in order
to raise a standing army upon its ruins." -- Debate, U.S. House
of Representatives, August 17, 1789
Yes, you are right, the correct o ring did turn out to be a white nylon
square cut. Which was not, unfortunately, supplied with the Fenco pump (and
they can look forward to a letter of complaint for that). The bloody thing
cost $3.00 at the dealer, which means it's what, 50 cents wholesale, how
hard would it be for them to use OEM rings.
Thanks to all for your input. I knew I could depend on you :-)
