To test to see if fuel was being ejected into the cylinder, I used a fuel line and attached an injector and turned over the strarter and look for fuel injection. And though fuel would pump, I've had no success getting the fuel to build up enough pressure to inject the fuel. Can anyone help me solve this problem?

Since you have utilized multiple injectors and two different injection pumps, I am going to conclude that neither of these components are the problem.
Therefore, the only possibility is the procedure utilized to install and remove the hard lines from the injection pump. The statement that the fuel is variable depending on "how tight the injection pump outlets are tightened" does not seem proper to me, however, I don't have the experience with this engine.
I will ask Peter to make a comment about this for you.
