The outer braid on hose like this is for abrasion resistance - pressure capability comes from the layers beneath. Not totally sure what you are doing inside your PC case that requires abrasion resistance.
IMHO, a SS outer braid is even worse unless you get the hose terminated by a professional with the proper tools.
You're thinking of using injector pumps? They're rated for continuous duty, right? All the injector pumps I've seen are fairly low volume, and are only at high pressure when pushing fluid against a resistance (typically a regulator valve - pressure pushes a spring behind the valve). You
do realize that injector pumps
rely on the lubricative qualities of gasoline?
I don't think that raising absolute pressure in a system is going to make any difference in thermal transfer. But it's always useful finding out if your assumptions are right or wrong so I wouldn't
think of standing in your way. I
would suggest, however, that instead of using fuel pumps, you set up a "normal" system - with the exception that you use a pressureizable reservoir (and, of course, set everything else up to be able to withstand higher pressure, so, yes, higher rated hoses, fittings and radiator - oil cooler?) For instance, there are anti-water-hammer devices designed to be attached to house plumbing. They are essentially a cylinder with water on one side, air on the other and often a diaphragm between. I've seen a few that appear to be set up so you can add pressure on the air side (schrader valve). Adding air pressure would indirectly pressurize your water loop. Much cheaper than killing a couple of injector pumps.

PS: Yes automotive sytems are pressurized a bit, but this is simply to raise the boiling point of the coolant, not to make the system more efficient at thermal transfer.
