THAT IS NOT THE ELECTRIC LIFT PUMP!!!!!! --- THE PUMP YOUR POINTING TO IS MECHANICALLY DRIVEN BY THE INJECTOR CAM WHEN THE ENGINE IS RUNNING and is not electrical at all.

THERE ARE 2 PUMPS --- THE GEAR PUMP and THE ELECTRIC LIFT PUMP.

The fuse you found and the horrible sound you hear is for the electric lift pump and not the gear pump. The electric lift pump is located to the right of the fuel filter on the CM870/CM871.

Okay so i was planning on getting both the gear pump and the lift pump but only put on the lift pump to see if that fixes the issue.

Thanks rawze!
