Fuel Manifolds

[Kerbal Fried Chicken]

I've been trying to expand my KSP toolkit by exploring parts I've rarely used. In this case the fuel manifold. I usually screw up either the fuel flow or the staging. I can't find specifics on the "Flow Priorities" tweakables, and I expect that's where I'm going wrong. Can someone give me a rundown on using the manifold properly? Also any info on how the flow priorities function would be much appreciated.

Tanks with the highest priorities that are attached to running engines drain first.

So if I have a central tank and two side tanks all with running engines and set the outer tanks to a higher priority the outer tanks should drain first?

excellent thanks for the help.

If I have outer tanks and no engines on them could I use the priorities to specify which tanks I want to drain first?

yup

And if you have decouplers between the side tanks and the core, you need to remember to allow fuel flow across them.
