I know this is might be stupid. But the fuel pump wires might be damaged. Did you inspect them when you changed the pump?
Possible faulty ECU. Try changing it with a known good one.

Also if your car has an aftermarket alarm system could have dodgy wiring. Check and clean pump earths, wires, bad connections, etc. Something has to be causing excess current draw for the fuse to blow.
Also may pay to take out fuel pump assembly check the connectors at the pump and check for bad connection/resistance in the wiring. The old pump may have drawn excess current and burnt a connector out. Look for discolouration or funny looking terminals in the connectors or the connectors themselves.
