I have been fighting issues with p/s pump leaks and failures for about 6 months now. Based on content in multiple threads in this forum, I have been in contact with several members via PM to verify part numbers, etc. I thank all of them for their responses.
The original OEM pump (I thought had failed) back in February. I got a replacement from Autozone and took it to a trusted shop to replace it. After he got it installed in the car (and before installing the p/s pulley, the shaft pulled right out of the pump. I took it back to Autozone and they could not get a replacement for several days and I couldn't wait so I headed to Advance Auto and got a pump from them. About two weeks after it was installed, leaking badly. Took it back and got a replacement. As soon as the shop started pouring fluid into it, fluid was pouring out around/from the EVO. When I looked at it, I realized the O-ring adjacent to the "tee" fitting that slides over the EVO was missing. Installed a new O-ring and everything was OK for about a couple of months. Then after the car set for a week while I was out of town, drove it about .1 mile and p/s started making very loud whine, then p/s gone completely out (and no more whine). Made it into Autozone lot and poured in fluid, which ran directly to the ground. I then drove it home and parked it.
I attempted to find the appropriate O-rings (all 4 of them) for the EVO based on input from a number of members:
Can anyone who has recently performed a successful repair of this leaking nightmare tell me where they obtained the 4 correct O-rings required to correctly seal this EVO?
Are 3 of these O-rings the same identical part? If so, the O-Rings in the Ford 391032-S kit (the larger O-rings) did not correctly seal my EVO into the pump or the sleeve onto the EVO. I suspect the 2 O-rings that are positioned under the sleeve should be identical in both inner and outer diameter. However, I'm not certain this is true for the large O-ring adjacent to the sleeve and just below it toward the pump body. Obviously the smaller O-ring toward the tip is a different part.
I previously purchased a cross-reference kit for AC DELCO 36351210 from Advance Auto Parts, however, none of the O-rings in the kit appeared to be the correct size for any of the 3 larger O-ring positions (2 under the sleeve and one immediately below it) on the EVO.
A mechanic at the shop said he spoke to another shop that said these pumps were notorious for leaks and the best option was to install a plug that eliminates the EVO. Does anyone know if such a part is available that is correctly tapped for the high pressure line fitting for the OEM high pressure line?
Any and all assistance is greatly appreciated. This is driving me (and the mechanics at the shop) nuts.
Best Regards,
Ted

Ford O-ring part numbers:
391032-S (Interchange for 389349-S)
I was able to obtain these and they appear to be for some of the larger 3 O-ring positions on the EVO
387571-S (No longer available)I suspect this kit was for the smaller O-ring toward the threaded tip of the EVO
Bowez then responded with part numbers 384975-S94 and 391032-S from an old service manual. I do not yet know if either of these are still available from Ford.

He is positive (actually went out and looked at his part number label from Autozone) that he used two of the Autozone Part # 8527 p/s pump seal kits in order to obtain the correct type and quantity of O-rings for the repair.
He also listed AC DELCO Part # 36351210 with a quantity of two kits required.

One of Kendall221's post's indicates the use of Autozone Part # 8526 for a quantity of 2.
