Update
I finally got some time to work on this project. After replacing all the rubber hoses, injector seals, and all gaskets and seals in the intake system, it still drains fuel into the intake. I took the advice of duxthe1 and decided to look for a complete fuel distributor in a wrecking yard, and replace it (rather than just replace the plunger seal). I found one today, and did just that. It does not leak into the manifold anymore, but it would not idle either. I adjusted the flapper (not sure exactly what it is called) a little by leaving the center bolt a little loose, and moving the flapper until the idle smoothed out. It idles great now, but it is really boggy, and does not rev up well. It also is very hard to start (cranks for a long time before eventually starting). It was slightly boggy before, but much worse now. Did I get a bad fuel distributor? Should I go back and get a different one and try it? The distributor was from a single cam engine, and mine is dual cam (not sure if that makes a difference). I am not sure where to look for cause of the bogging problem. Anyone have any ideas?
