Make and model? Does fuse blow as soon as key is turned on, or when key is turned to start? Or after engine is running?
I see you gave me all that! Ok. Does engine die as soon as fuse blows? If it does, check the fuel solenoid in the carburetor , to see if it feels hot. It can be shorted out, blowing fuse and killing engine. If not the fuel solenid, next would be to unplug the voltage regulator and run test with it unplugged.
