Does the level drop after you pull the fuse ? It's coming on for a reason, or a short in the system. It needs to be checked to find the reason for the issue.

Possible the level switch may be bad. Not sure just guessing.

I have had to change the control modules before for different reasons and the pump is attached to it so it could be the whole unit needs replaced. Have it scanned to find the proper area to start and give us the codes that we might help further.
