Thanks for the reply Carl.
I am almost done with my power steering lines.
I am still waiting on my 11/16x18 fitting for the supply side. The hoses were made at Napa. They are made with 5000 psi hose which is overkill but they will serve just fine.
I used a metric fitting that converted to a 5/8 fitting.
They ran me right at $90
M16x1.5 fitting that converts to 5/8. This was used on the ls1 pump side.
11/16x18 supply: 27" of hose + fittings and 90 degree 3/8 steel tube.
5/8x18 return: 17" in length of hose + fittings to connect to ls1 barb on pump.
