Had a Durr moment... Bad fuel pump now?

[69gmc-IN]

Ok, So here's the deal, I pulled the old gas tank from my 69 GMC 1500 because it had about half an inch of sludge in it. While I had it out I got the bright idea that it'd be good to blow out the rest of fuel system to try and purge any crap that go left behind. I unhooked the fuel line from the carb but still left it hooked through the fuel pump, now after reassembling everything and a fresh new tank/sending unit I get gas to the fuel pump after using a little hand pump to prime the lines but can't get the pump to push any gas to the carb. Did I blow the diaphragm or valves in the pump using compressed air on it?

It's a 250 I6 engine if it makes any difference.
