Thanks everyone, found the answer.

I did originally speak to the Dyno shop and they only had the GM electric pump, nothing to connect a ford SB.

I spoke to Turn One Steering who rebuilt my pump and they have confirmed that there is no issue at all with looping the pump. The rack has a by-pass when driving straight and pushes low pressure fluid back through the return. When the pump senses resistance, the pump builds pressure.

Hope this helps others, and thanks for the replies!
