Fuel pump not working

Last Labor day my truck just would not start. It would crank good and hard but would not fire up.

Through some "internet searching" I found that this was a common failure and that it was caused by overheating to fuse #27 (fuel pump) slot itself that fried the fuse and the socket as well.

I pulled fuse #27 replaced the fuse in the same slightly melted socket and it fired up and has run flawlessly until now.
Last night I left the keys in the ignition and in the "acc" position. Battery was drained but even with a jump it cranks but will not fire again (it sounds exactly like it did when the fuse melted).

I replaced the fuse, no joy.

I seem to recall hearing that Ford made a "Fuse Re-Route Kit" to somehow "move" fuse #27 from that slot into one of the spare slots in the box.

Thing is I cannot find word one about this re-route kit. Starting to think I imagined it. Any words of wisdom would be greatly appreciated.
