so the rx7 pump has two pressure lines. and one return. The steering rack then has three ports on it. Two are pressure, one is out to the cooler then back to the pump.

With the swap i am doing ( miata engine) , my pump has one pressure line out, like a normal car.

1.) Why are there two pressure lines in the first place.
2.) any thoughts on how to plumb this arrangement?.

Just block the extra port, worked fine on my 1jz fc
