Yes. The Ford f250 cooler is a good fit.

Yes. Just make sure that the cooler is below the reservoir and that the cooler is situated in a way that it won't trap any air bubbles.
I cut 5" out of the low pressure side of the paper clip and put my cooler "inline" with that. My cooler is attached to the radiator.
You really can't see much, but here's what I did.
For the couple of people that have done this...how did it effect road feel and steering speed?
Steering is a little slower to respond and also you have the feeling of a super duty type steering damper. Road feel is okay.
Doesn't sound like a win. Would you do it again if you had to?
There are ways to help with issues like that. Usually involves drilling out a restrictor plate in the pump to increase flow (this is what I've been told...no personal experience), I haven't seen the inside of the 80's pump to determine if it's a possibility. You could also add a belt driven pump from PSC or similar that has better specs than the OEM one.
There are options...

Absolutely. I can steer from a stop and I only trailer my rig
Reason for my hesitancy....
I realize fluid dynamics plays a role and sizing a ram to the pump output could address the on road sluggishness of the steering.
In talks with ram suppliers, the pump was always stated questionable, regardless of the fluid capacity, as it can only keep pump so much before the ram (best I can described. Not technical) sucks more than the pump can push.
Can't increase the pump flow, as scotia proved.
Can't change the pump.
My question is, wouldn't the cavitation be pronounced enough to hear during normal driving?
Do you hear it on road?
Based on what scotia posted here and several phone conversations, he said he'd maxed out the pump to the point it blow the seals off on the bench.....but concern was blowing the seals installed.
In the post above, I guess I should've clarified there's no way to elegantly swap pumps, as a belt driven would be easy enough to swap, but no alternatives for an OE configuration.
Where I left off, before the other projects consumed every waking moment and all money, was looking at the dual ram, since the cylinders are smaller and a constant fluid push, not a vacuum.
Can't recall the company off hand, but in email communications, they eluded to there being substance to that theory, as it requires less fluid and something about the fluid dynamics to a push/push versus a push/pull.
Slept since then and none will work with the arms I have, anyway, but it begs the question if a smaller ram, requiring less capacity, would provide enough benefit to justify off road, while not feeling the affects on.
I've not heard the pump working since the install of the ram, in fact it's quieter than it was before.
I did drill out the restrictor in the pump, but doing so only netted a small gain pressure. My next step is a smaller diameter pulley, but as Scotia proved I can only downsize about 10% before cavitation and noise become a major factor.
On to what you've been putting together in terms of your system. I think you're going way overkill on how much fluid capacity you're adding to your system. The heat-sink style cooler, extra reservoir, ram, and additional lines are such an increase in capacity you're going to have to carry gallons of atf as a precaution.
With the heat-sink I'd omit the extra reservoir. Jmo.
I have been reading every thread I can find on adding Hydro. Some are saying use a 1.5x8 ram, others 1.5x10. I don't want it too long such that it goes all the way to the stops, I would prefer the ram to create the stopping points.
I have already upsized my reservoir, and looking for a good cooler unit. thinking of the derale unit.

What size should I get, and any sources out there?
Thanks,

With the 8" ram I adjusted my bump stops to stop travel mm before the ends of ram travel. Too long of a ram can press your knuckles right off the axle.
