Slip the clamps over the new hose.

Then install the new hose fully over both of the connections - one at the power steering pump reservoir and the other down at the steering box.

Tighten the clamps to finish the installation.

At this time you may want to consider using some de-greaser to clean up the driver's side motor mount and the engine cross-member as they will be covered in power steering fluid. The oil may lead to premature failure of that motor mount, in particular.
