Rattling Fuel pump?

[zombieman]

hey guys, i change my gas tank yesterday since there was a big as dent on my old one that cause the fuel pump not pick up gas properly. well, after changing it and reinstall the fuel pump, i start to hear these rattling noise. i can't figure what it is. my assumption is that the pump broke and now the fuel being deliver through the hose is not going through at full capacity, it sounds like their are air also traveling through the hose. I can hear it pretty loud since i also took off my back seat out yesterday.
