Don't know what the picture in my first post is or how it got there. I didnt put it there.
Thanks for your help.

I don't have the same brand of hand held vacuum Tester; but it works the same.
I only have the V Tester and it did not come with the brake bleeding reservoir. So I made one from a Jelly Jar and some plastic vacuum fittings and used Eopxy to hold them in place.
Anyway, it woks well for Me. I back off the Bleed Screw just enough so Fluid will pull through it. However, it is true that some Vacuum also gets sucked around it but in the end that does not matter.
You can be patient and keep pumping till Fluid comes once you see that the Fluid Level in the Master Cylinder is dropping you can simply walk away and let gravity do the job.
That is usually what I do and come back and check the Fluid Level in the Master Cylinder.
I also think that the fluid reservoir that comes with the Mighty Vac type tools for brake bleeding is too small as I like to bleed until I see clear fluid coming out.
