Fuel pump connector issue caused troubles with last one I had. We had a few issues but the connector repeated.

You could inspect each connection from the fuse to the pump to see how yours is failing, if it is working hard to try and pump dirt, you have the best luck cleaning the tank, replacing the pump filter. Clean and test the pump. wiggle test the connector to see if connector fit is loose creating resistance and requiring more. The amps flowing is what melts the fuse, but that is not to say there is no chance of a chafed wire. you could try to reproduce the fuse blowing during the wiggle test of every affected area of the harness. Try a schematic diagram, note each connector, find it, inspect and expose it to views and testing, then run the circuit and search. Time consuming and not a definite call, so your mechanic cannot give a satisfactory answer without either taking it apart, tearing down the tank or going for the pump and its filter as well as the system filter. Relays for fuel pumps can cause issues as well. arc ing in the circuit is caused by poor connector fit sometimes. careful search is best precheck., I think.
