Plumbing:
Pretty cut and dry the large low pressure line goes from the reservoir to the pump from the large openings, the high pressure line threads in the pump and then threads in on the pump, from the pump the low pressure line goes to the lower cooler line then comes out and goes back to the reservoir. Once all connections are made and tight including all the low pressure lines and the high pressure line go ahead an fill the reservoir with power steering. While finishing up putting everything on watch for gravity leaks and fix as required. This will also help in priming the pump and box keep an eye on the fluid level and add as needed.
