I belive I've gotten the ck valve delima solved.I used a rope type gasket, mostly used in plumbing problems to seal the two haves together.We'll see later.I'm now having a problem bleeding the stinking thing.I bought one of those One-person bleeders and just can't seem to get all the air out.Should it take more than one lg container to fill the whole system up?Does the hydrovac hold a lg amount of fluid? I started at the longest line first and worked to the closest(left front).Then bled the 2 bleeders on the hydrovac itself. Still no Pedal!!!!!!!I was told to leave it a day or so and the air bubbles will move to the highest point.I don't know,I'll try anything at this point.
