We have the stainless steel lines and fairly new rubber lines on it. I think I found the problem, we have fluid and pressure on both sides of the line lock solenoid, however when you get to the pressure delay block I have pressure going in, but nothing coming out, no matter how hard you push the pedal.
I am guessing the valve is stuck in there because as I understand it, it should allow pressure through over 125psi.
Now, to find one of those things........
