The fluid leaked out of the tubing fitting from the isolated side of the isolator. Found antifreeze fluid leaking out. That's why I now have no pressure. Won't have a chance to rectify till this weekend.

Very common issues with isolators...

The other one is the anti-freeze will leak into the fuel and then fuel will replace the anti-freeze and you'll never know it.
