If the FUSE is blowing it is from the FUSE to the Pump. Either pump is going bad again(read if you used cheapo AutoZone parts) or maybe wiring is chafed by the tank. Your new pump came with new wiring to splice in wasn't it? If not done correctly may be rubbing and shorting but to me sounds like FP is going bad.

Possible wires maybe chafed now, but sounds like pump is shorting out.
I can remember a few with wire issues near connectors at the tank and where the spliced into it. Short of that cpuld check the fuse panel for corrosion especially under it (if pump fuse underhood).
