Most likely will outlast you or I

All it does is jumper the contacts of the fuel pump relay It is fuse protected
When you remove the key or turn the key to off, all power is removed to the jumper
But I would replace either the relay or fuse box to be on a safer side.

I did replace the fuse box, no dice. As long as their aren't any long-term effects to the fuel pump or electrical system, I'd like to wire up a hidden kill switch in place of the jumper.

Used out of wrecked Expedition plus i made sure the wreck didn't beach the window or door to allow moisture to foul the fuse box.

Edit: I've purchased a replacement fuse to rebuild my original fuse box with.
