The loom was sub standard to start with leave alone now! The main problem is the span of the switch, it brings the fans on to early then keeps them on for agaes, which causes the fuse to melt.

The problem only arises when stood still for a period in traffic etc if you don't have no fans, I am surprised it has never overheated as the temp rises rapidly when they are still, obviously when moving the fans are not required.

You can buy looms pre made or DIY, basically rewire, diden't know MSD sell the looms but they do "Sell" uprated switches.

Another thing to look at is the fuel pump wiring, this builds resistance over time and the pump cannot draw the power it needs thus you do not get the required fuel delivered!
