Problem with Mity Vac - Help! I went to Advance Auto and bought a "one-man bleeder" kit, a Mity Vac with a different name, and I have run into a problem. I can not create pressure, ie no vacuum, when the whole setup it together.
When I attach the first hose to the pump and block off the end with my finger, I get a vacuum. If I connect the other hose that one and block off the end of the second, I get a vacuum with both. But if I attach both hoses to the fluid cup and block off the end that would go into the reservoir), no amount of pumping creates a vacuum. I even attempted to create the vacuum by putting the end into the reservoir as you would when you start bleeding, but came across the same no vacuum result.
I am 95% sure this means there is not a seal with the lid on the cup, but I am trying to find out if anyone else had this issue and what you would recommend to solve this problem.
Any advice is appreciated. Thanks.

Not sure but, do you have that little hose on inside the cap and fluid in the cup? Did you try switching the hoses from one side of the cap to the other? I think it matters which side the pump is on...

Yeah, I followed the directions with which side to put the pump hose on and which side to put the reservoir hose on, but it's not working. I suppose I could try swapping them just for the hell of it. I also tried it with various amounts of fluid in the cup.
I believe the reason it matters which side the pump is on is because there is a short hose inside the cup on one side, as well.
If you blocked of the end of your reservoir hose when the whole thing is hooked up with your finger, do you get a vacuum? I'm assuming it won't work without that vacuum.

Well, I know not many probably care, but the issue ended up being that crappy piece of equipment I bought from Advance Auto Parts. I went to Napa and got an actual MityVac, so I was able to use this.
The strange part is that I got one air bubble to come out (nothing major, but something), but then when I released the pressure before pulling the hose, not all of the fluid that came out would go back in. So, I pulled plug, ended up filling the reservoir, and still had a bunch in the tube from the master (????).
The pedal felt SOFTER after this, so I pumped it a ton of times to check if it would get work in but it didn't seem to get much better. I decided to take it for a test drive and after 15-20 minutes or so, it seems to feel fine again (just like it did before I did anything).
It shifted really well 1-2, alright 2-3 (always been a bit fussy), and alright 3-4, so I guess I can't complain. I was hoping for a better result on the 2-3 and 3-4, but it feels pretty much the same as before.
