New infill desired- "fuel cell" type permiability
I find myself designing cavities designed to hold water. The challenge is when I cannot make the 45 degree min angle for the "roof". I find myself having to build structure to avoid long unsupported sections. An infill pattern that works like an open cell foam such as they use in aftermarket fuel cells for dragsters etc.
Is there a sleek way to do this with existing infill, or maybe this is a common desire?

I'm not sure of what your looking for, no image's no examples shown. However If you design carefully and have a good mastery of PrusaSlicer, you should be able to print angles of 60° (that's 30° on the Protractor) without much problem, even if you can't manage that 55° (35° on the Protractor) should be easy to obtain. There are also techniques that can be used for temporary support.
Good luck

I am looking for an infill that allows water to move freely within it. Imagine a square box with an inlet and an outlet, and some sort of infill that lets you fill water in the top and it runs out the bottom outlet with very little resistance to flow.

I would think that a low density Gyroid infill would allow this, and act as a baffle to stop sway & splashing. If not, you could certainly alter the infill (any infill) using modifiers. Say for example you were using a standard Grid infill of a given density, you could use a mesh modifier to create channels along to bottom to allow for even fluid distribution, doing the same in a lesser way along the top to prevent vacuum or pressurization.
