Stuck in the up position would release the most fluid to the rear brakes.

I have mine tied upward with a zip tie.

even holding it up and pressing the brakes it still will not allow brake fluid to the drums

Sounds like you need to flush your lines. Something clogging them. :twocents:

remove it  and  plum the line in direct,  if you have  big tires  you dont need no stinking proportioning valve :gap:

dont worry about them, they are a non issue.... they are return lines and things like that... if you jsut run a line from the mc to the rear, there is no need to touch any of the oterh lines
