Hey guys. I finally got my 400 going in the 77! I redid the wiring and got it to turn over fine now and itll fire right up IF I put gas in the carb but it dies right after that. I pulled the fuel line off the carb and its not getting any gas. I know that the fuel pump is good because it was on my 350 and it ran fine. I pulled the line off the fuel pump and it was dry also? There is no gas getting to the pump itself. Anyone have any ideas? Any help would be greatly appreciated!!! Thanks guys, Josh
