To address everyone's comments . . .
I live in Virginia - so I see from the 20s to the high 90s. The inadequate assist issue has been popping up while the temperatures have been in the 40s, but it only happens when the vehicle is warm, and doesn't seem to happen all the time. With a little RPM the assist seems to come right up but, obviously, in a parking situation a little RPM isn't always possible.
As a caveat, it was my intention to get rid of the EVO just to simplify things and not have to pay to replace it. I understand that the EVO system can work fine if installed and maintained properly.
That said, had I not already bought the parts (for a 1998 - Cardone 208748 - I'll discuss that below) and then let them sit such that I couldn't return them I would have:
1) Bought a 1996 Pump.
2) Bought a 1996 Line.
3) Put in 2 gallon per minute adapter.
(and this is what I would recommend to anyone looking to get rid of EVO).
That said, I'm not convinced there is any difference between a 1996 and 1998 pump. If you look at Rockauto this is 1996 options from Cardone:
If you look at 1998 these are the Cardone options:
It seems that the base pumps are different (2 different part numbers, 20661 v. 20860) - though I've heard some people express skepticism that they really are different (I assume there is some difference).
The second option for 1998 (208748) is the one I bought (that was a mistake - my reservoir was fine . . . and since I wanted to delete EVO I guess I should have bought 208748VB . . . or perhaps the 1996 pump option, which perhaps would have eliminated the need for the speedway adapter . . . this all gets kind of confusing and I don't know what the difference between the 1996 and 1998 pumps are (gpm? something else?).
The 208748VB looks like this:
The 208748 looks like this:
I believe the difference is - and should be - the adapter that you can kind of see in the first picture, that isn't in the second (there isn't an adapter underneath the blue cup in the second picture). I believe that adapter will allow you to go directly from the pump to your line (preferably a 1996 for ease of fit) without an adapter.
I ended up essentially getting that adaptor - with reduced 2gpm flow (compared to 2.5gpm, apparently - at least for 1998 - maybe it's less gpm for 1996 without the EVO) - from Speedway.
Regardless, as it is I have a 1998 pump, a 1998 line that I "adjusted" to fit (works, not ideal), and the 2 gpm adapter.
With these parts it's functioning fine (and I think the highway feel is improved - even over when my EVO was functioning properly) . . . except for an occasional issue of inadequate assist at parking speeds after warm.
No one has jumped in this thread to say that their experience was similar to mine (though there probably aren't that many people out there that ended up with this mix of parts), which makes me thing that the issue for me is probably something other than issues with this parts. Especially since the problem is intermittent (that is, I don't have the lack of steering at low speed all the time).
Hopefully this review of this will help someone looking to do this in the future. I kind of stumbled through this thinking I knew what I was doing, parts-wise, without really understanding everything I needed to.
