If it had the valve, it would have the two threaded mounting holes, as seen in post #48.

That's why a thought that it was added later. I never knew that hic-PORTs without a valve even existed. Since thisTQ obviously is remanufactured it's not sure that the parts were originally together. Now I know how to deal with it.
