Pressure out the pump is NOT like the PSI inside the transmission. It is only like 45 PSI out the pump back through the return.

I realize that it's lower in the cooler ciruit, and how much pressure is neoprene fuel line rated for when it's hot out with hot fluid running through it.

I said hydraulic hose as a coverall but I'm pretty sure there is something in between fuel line and commercial hydraulic lines that would work fine.
