Sorry. Clearly I overlooked that part. Then yes. Just run a new wire from the relay to the fuse. If you cut the wire about 3 inches on both sides then you can just solder in a new wire then shrink wrap it. Do not use butt connectors. They will fail.
When you cut the wire from the relay, you clearly want to make sure you have power on that wire. If not, then you probably have an issue with the connection on the fuse box. However, this is unlikely. I suspect you have a rub through on that wire from the relay to the fuse which is grounding the wire not allowing the power to get to the pump.
The only way this is not safe is if you use some of those relay jumper terminals. Those are meant for testing which means they are temporary.
If you cut and solder the wires then protect the solder joint you will be fine because this is the proper way to repair wiring.
Let me know if you have questions about this. Thanks
