Default Mityvac wont work

Ok im having some issues with this mityvac. Its not holding pressure, i pump it up to 10 and its slowly leaking out. It sounds like air is coming out around the resevoir. I have it hooked up correctly and i am doing the process correctly its just leaking air it sounds like... Is there any tricks to keeping it from doing this? Its pitch black and im in the middle of doing this and i kinda want to finish it tonight.

The fitting at the reservoir doesn't need to be super vaccuum tight since it's only there to drain fluid to the master but zip-tie the line if it lets you sleep at night.

I've never needed a MityVac to bleed an LS1 car. Put the MityVac on the shelf and use the JMD Method

do you have any pics to refresh the picture in my mind

I get lost at this point
Once you've replaced some fluid, remove the hose from the bottle.
Place it into the clutch fluid reservoir so its end is pointed down and submerged in fluid.

Get rid of using that and do the 2 person menthod, you can also search for Gravity Bleed. I have posted a few how-to's here on that.

Default JMD method

so if I have a tick speed bleeder hose I can open the bleeder screw and let this drain into a cup on the ground first before moving it up to the reservoir?

I have a new tick MC and slave and when I tried this at first nothing came out. I will need to try again but from what I am reading with this method it should just flow out of the slave. Makes sense, just isn't happening.
