Man, I'm sorry you're having so much trouble. These pumps are really fairly simple. I can't imagine a delivery valve failing.

One thing you can do is dead end the return line to the tank. The fuel pump is just spring and cam powered and it's the spring that pushes the fuel, not the cam. So, you won't hurt anything by blocking the return.

This is provided of course, that the air is purged from the system (no bubbles out the return line before plugging).
