Boolean union keeps failing on this file and i cant figure out why. Both are closed polysurfaces and the internal section was split by the curve of the exterior so they should be intersecting. anyhelp is appreciated

everything you need to know about why your boolleans don;t work can be reveled by running the intersect command on these two parts.
see the resulting curves- notice that they are not closed.
this means your intersections are not able to create a closed intersection which will immediately make a union fail.
To fix it, increase the overlap between your two parts so that they intersect completely. Either scale you inner part up a bit, your outer part down a bit or extend the “legs” of your inner part a bit so that they are a bit longer.
a tiny scale in the length and width made this work-
