Yes I have tried a new manifold valve , replaced the tractor protection valve. And still something is back feeding to the red button.... And if I plug the red line off and push the red button until it has lots of back pressure, and pull the yellow one out, then it too has lots of pressure and won't stay in

It must be killing you to just have to sit quietly
Start unhooking lines off the valve and see where you have air coming from.
