It's here. Does it look like a hydro boost line coming off the pwr steering pump?

Away!
Hmm. Not sure. Its definitely 03, not 06, though. Clutch fan.

Agreed. I do have a set of stock electric fans--but that'll have to wait.

All nbs 3/4 tons had mechanical clutch fans iirc
Don’t think they ever got e-fans until the nnbs trucks

Ah. Didn’t think about that.
On my 5.3, the output of the PS pump (the lower hose on the PS pump) goes through the steering gearbox first, then up to the hydroboost from there. The output of the hydroboost is the return line, connection circled in red below. Not sure if that's a hydroboost pump or if they're different.
EDIT: I might be wrong about that, but the hose that is attached within the red circle certainly seems to be the right length to attach to the hydroboost unit.

All the better for smoky burnouts!

That hose at the top of the PS reservoir is the return from the hydraboost.

my old 03 failed at burn outs. it had a locker and it had 33's on it that were 12.5 wide bfg's. no smoke shows till the back tires were bald. or on wet leaves.
but it would pull stuff damn good, i should have bet money the day we needed to drag a bob cat skid steer 10 foot out the way on loose gravel. my truck was like a dog tied to a stump, still moved that damn thing.
