Edelbrock 1406 Not Pulling Fuel into Carb

Hey All,

I'm sure there is something simple and obvious I'm missing but I am still stumped. Long story short, after putting the carburetor back on, I wasn't getting any fuel into the actual carburetor when pumping the gas. Not even into the fuel bowls. I disconnected the fuel line from the Fuel Inlet and manually sucked fuel from the tank to make sure it wasn't something down the line towards the fuel tank and that was all good.

I then, manually filled the bowls to see if the plunger would do the pump shot and that all worked fine as well. I also made sure that the floats were NOT stuck up and I actually blew air into the fuel inlet to make sure that circuit wasn't clogged. Is this a sealing issue between the Air Horn and Body Assembly? Theoretically speaking, if I manually pump the plunger, shouldn't I feel a suction if I place my finger over the Fuel Inlet? Because I'm not feeling any suction.

The grooves on the Air Horn, that push into the gasket, are worn down pretty bad, could this be the issue? In the photo I attached, the area circled in red is where the groove is warn nearly all the way down.

Thanks for the help.
