How to model an internal volume of assembly

I'm having trouble pulling the internal volume of this assembly.  I have tried multiple approaches using Intersect, Cavity and Surfaces with no luck.  I feel like the surfaces command would be my best bet but whenever I'm trying to offset the surfaces, it says that they are not touching (which is true).  I previously was able to get internal volumes in Autodesk Inventor by using a surface offset and then patching the distance between surfaces.  Is there a similar way to do this in Solidworks?  Attached is an example assembly of the volume I am trying to find.  The target assembly is Inlet Manifold Volume Test.


Thanks for any help!
