I Am Not Getting Fuel To My Six Pack

I have been chasing down what I thought to be a vacuum leak in my 440 6 pack setup. In the process the fuel delivery to the carbs has become less and less until now I have no gas to the carbs.

I checked the split at the carb inlets and nothing. I found a filter just before the pump an disconnected it on the tank side. I was expecting a lot of fuel to come out but none.

After putting air into the gas tank I can get some to come out (but not as much as I would anticipate). I did replace the pump last night, but still no fuel.

1)I'll run a hose from the pump to an open container and see what I get.

2)I think that I could run a hose from a container of gas just before the pump and see what I get

3)I'll remove the filter on the tank & pump side then blow some air into the tank to check my flow.

4)I think would then check the fuel vapor lock separator to see if I have feul coming through it.

Anybody want to take a stab at this.

Blow out the line from just before the pump to the tank pickup. Might be a plugged tank sending unit sock or maybe the pump pushrods or cam lobe is worn
