Soldering these in is nearly impossible, we install these into the casting with JB Weld.
We warm up the radiator casting, install the neck, and then put the JB Weld around the outer edge of the filler neck.  The heat from casting will warm up the JB Weld into a thin mixture and lets it flow into all the voids really nice. 

Please ask if you have any questions about the part and application of the part.  We will be more than happy to look it up with your model and Serial Number and to help in any way we can.

We use these in our tractor restoration and repair shop and these work great for us.
