Oh, I had that backwards. Any chance the RF hose has an unusual twist 
in it, or that you twisted it a lot to get it installed? Excess 
twist, even temporarily, can damage a brake hose.

To install these, you have to free up the line nut on the end of the 
hard line, so the hose can be installed with just the right amount of 
twist, so it can hang right and not have excess twist or touch 
anything as the suspension goes up and down. All the turning must 
then be done to the line nut.  

You also mentioned that you were doing all your bleeding alone, using 
a stick on the brake pedal, which makes me wonder how you were able 
to insert the stick and watch for "squirt" at the same time.

To bleed alone, you need a couple feet of clear plastic tubing that 
will fit over the bleed valve, loop up a couple inches, and then go 
down into the bottom of the container you use to catch the old brake 
fluid. Then you can sit in the driver's seat and just pump the pedal 
a few times with the bleed valve open. This works just fine, as long 
as you check the reservoir occasionally to make sure it doesn't get 
low and suck air into the master cylinder.

After a few pumps, you can get out and look at the hose. The upward 
loop should be filled with fluid, but any bubbles there indicate air 
that's coming out.

The upward loop keeps you from sucking air back into the cylinder on 
the upstroke of the pedal. If you have 2 people, you should still use 
this same method, so you can watch for progress and bubbles.
