OK  I've read all the posts on making my own home made power bleeder from a pump spray bottle, but one question I can't find an answer to:  Do you need to leave the siphon tube INSIDE the bottle so that when you pressurise the fluid is fed to the master?  None of the step by step instructions I've read made any mention of this.  I've never used one of these before so forgive the stupid question.

Not a stoopid question at all. But Yes, you need the tube down in the fluid in order for the fluid to be pushed up to the master cylinder under pressure. I don't know what kind of sprayers folks are using to make these, but the material used for that tube may or may NOT be brake fluid compatible.....it may melt over time, so you may need to keep an eye on it if you store the pump for long. If the tube is metal, then that won't be a problem.

my home made brake bleeder is the simplest  one you can make. you put 4 old tee shirts on the floor under the bleeders and open them all up topping off the master cylinder as you go. when one runs full shut that bleeder and watch the others. when the inner rear is done open the outer until they run clear. it doesn't get simpler.

Yes, I plan to "gravity bleed" and have the pressure bleeder as a backup.  Question when you gravity bleed how do you know when all the air is out if you just let the brake fluid drip onto the rags??

You'll never get "all the air out" by gravity bleeding one of these cars. It just helps get the fluid down to the calipers. The design of the rear calipers requires bleeding both sides, unlike the fronts, which is only on one side.
Pressure bleeding is the best and quickest way to get the job done on these things....period(imho).
A trick on doing the rears, regardless of how you accomplish it, is to use a small rubber/plastic mallet to tap on the caliper while bleeding to help dislodge any air bubbles that are trapped, or clinging to the walls of the caliper....them little bubbles are sneaky! Bleed the outer bleeder first, then the inner bleeder.

inner first then outer, you bleeding from the source not the outlet. you absolutely can gravity bleed the system . when all the air is out its out.  just bleed it till you don't see any bubbles in the expelled fluid. you can use some clear tubing it makes it easier to see the air bubbles, im too cheap to run out and buy any.
