Cracking the fittings on the FD is a good idea. Believe they just screw in - at least they do on my '81.

It just occurred to me that you might want to check the flow to the cold start valve - that's where the engine gets fuel on a cold start.

IMHO, you are going to have to deal with the injectors and lines.

As a compromise, you might remove the lines from the FD, and clean them out - whatever foul stuff is in them is going right to the injectors.
