Need some help with bleeding the brakes.  I have replaced the nylaflow tubing in my L-IVP and  I am having a problem getting fluid back into the lines.

I originally started from the bottom  by attempting to pump fluid up thru the fitting on the brake housing.  No luck;  wouldn't take the fluid....big mess.  Next, I filled up the reservoir and tried to fill the lines from the top down;  by pumping the hydraulic cylinders on the rudder pedals.  No luck...bigger mess.  It seems like I am trying to push the fluid thru a check valve, the wrong way.

Funny thing is that I can remember years back when I first installed the brakes, I ran into the same exact problem.  Cant remember what exactly solved the problem but history seems to be repeating itself.  Guess the memory is worse than I thought.  Can there be a sequence to bleeding these brakes that I'm not aware of?
