Great write up! You just need to add one step:
I pressure test all my lines before installing them. I cap both ends with one end having a schrader valve. I pressure test the hose to 125 psi with shop air and dump it into my shop sink under water. If no bubbles it's good.
This has saved me a huge amount of time. I also pressure test all my tanks with less pressure before installing them.
It is much easier to fix the hoses and tanks before you fill them with oil or coolant.
