Power steering plumbing question. Ls1 engine. I'm trying to hook up an aftermarket off road R&P unit. The factory power steering pump has a threaded fitting and a clamp on fitting. My rack and pinion has 2 threaded fittings, one a bit larger than the other. Generally do the R&P have only 1 pressurized inlet and the outlet is low pressure? I assume the power steering threaded port goes to the RP larger fitting and then a low pressure return. Any thoughts?

You're on the right track but I don't think you can determine which fitting on the rack is pressure or return by the size - do you have access to the manufacturer to ask the question? Are the fittings on the stock rack two different sizes?

Yes, on the rack there is one 8an and one 6an. So there is one side that is not high pressure? I just assumed both would have pressure. I'm trying to track the manufacturer now but there are no markings on the unit. It actually is an in line unit that assist the steering then a rod goes to the rack.
