LS Camaro Tank Fuel Pump Question

[1970Chevrolet]

I hope this is the correct forum for this question. I am putting a 5.7 vortec engine in my 70 c10 and I'm going to use a gas tank from a 2001 camaro that I already have on hand. The only problem is that the fuel pump module has been dissected by the PO. The plastic module is there but the electric fuel pump and everything else attached to it is gone. Is it possible to put a new electric pump on the assembly? I wanted to avoid buying a new assembly since they are so overpriced. I tried researching but I couldn't find any information on how to replace just the electric pump only. Any help would be appreciated. Thanks.
