Yes when it's buzzing it is completly closed and ready to pull the connector.
Any pressure on return line directly increases pressure on feed line. Remember when you pinched your return line?

Yeah, I understand that, but if there were, say, 5 PSI due to backpressure from the return line, it doesn't seem like it would make any difference. If I'm keeping 11 PSI at idle, when the least fuel is being used at the injectors, I think I'd be okay everywhere else. In other words, if I don't go over pressure at idle I shouldn't have trouble off-idle when more fuel is being used.
But if there's more to it I'd like to know. It wouldn't be too difficult to used 3/8" line all the way back if I really needed to.
I don't think that is your issue. If it were you would be over 11-13 PSI. Read other thread.

Weird how the GM test procedure warns not to use 12 volt?
I need to build another test bench to have one running all the time, becuase this one is down half the time while building systems...
