I would pull the end cover off the carter fuel pump and look at the vanes. you could have debris in one of them, thus the low output pressure.
something is taking your pumps out.
The first pump was too high output. This one I checked before running it, off a jerry can.
Fun fact though. I noticed that michigan motorz is selling my setup (newer 4.3 with 1409). I called to ask about their jetting. They said they run the 1409 straight out of the box. I've been on hold with Edelbrock for an hour now to try to get in touch with their tech support...
