Per my manual #30 is PCM power relay.
Sounds like a job for experienced electrician.

I bet you got a diesel...check out the 7.3L forum...i think that also goes to your fuel bowl heater, pull the plug on the fuel bowl and see if it still blows...i may be wrong, so i would recomend searching the 7.3 forum its a common prob

Tyler is right on this. Your fuel heater inside the fuel bowl is blown. Like said unplug the plug on the heater bowl and replace the fuse. You can drive with the plug unpluged.
