Emery,
This was the change when he installed a macerator and moved the valve away from the tank, but this style repair could be used with the original valve. If you do work in this area be sure to use 316 ss bolts and nuts and washers. As Dennis has said, that would be the adapter to use as it uses an O-ring to provide the seal. I need to check with my local RV shop, he always has stuff hiding around.

Thanks guys, failed to clarify early those were not my pictures, but merely for reference...but your answers still gave me what I need to plan.
Unfortunately I think my tank already has had the revision Dennis pointed to by Emery, it has the long bolts with flange, and the drilled out tank pieces are broken open, and the top pieces are pulled apart too.
The epoxy is a logical solution for nylon to black plastic, but if that piece isn't available, I may have to do some nosing around as well! I am about to learn if gloppy silicone will last at least one more trip - ha!
