Thanks for confirming that I should expect it to work - I wasn't sure if it was a Kerbalism thing, since I've just started using it. I worked out the problem - when I did a clean reinstall of KSP I hadn't remembered to enable "advanced tweakables" in the settings. Once I did that I was able to set the flow priority and manually transfer oxygen.

How do you manage the flow of oxygen between parts of a vehicle? I put a fuel cell and 2 pressurized tanks, one with oxygen and one with hydrogen. When I turn the fuel cell on, it draws all of the oxygen from the command pod and drains that before starting to use the oxygen from the tank. I'd like to configure it to prioritize draining the tank first. At the least, I'd like to be able to manually transfer oxygen from the tank to the pod. The tank is on a part that gets jettisoned before reentry, so poor Jeb struggles to breathe on the way down. I'm using stock KSP 1.12.5.3190, Kerbalism 3.19, and a few mods: - Kerbalism-Config-Default 3.19 + CommunityResourcePack v112.0.1 + Harmony2 2.2.1.0 - KerbalChangelog v1.4.2 - KerbalEngineerRedux 1.1.9.0 + KSPCommunityFixes 1.35.0 - KSPRescuePodFix 1.6.4.14 - MechJeb2 2.14.3.0 + ModuleManager 4.2.3
