LD4B Intake question

Now, I did find something interesting. On the older water pumps sold now, new/rebuilt (?) today. They come with an adapter. The gauge sensor will screw into the one adapter which screws into the second adapter and will screw into the by pass house outlet on the intake.

As pictured below, the trick is to get the black pipe threaded adapter with the inside of it ready to accept the adapter that the gauge sensor screws into. I don’t know if this is an easy to get item. Threads on the outside and inside.

You can see below on the older style water pump the black adapter in the water pump and then the hose end screwed into it.

Same deal on the intake plus on adapter fitting.
