Follow the wires up from the fuel pump to the front of the car. You most likely have a wire that rubbed though its coating somewhere and is causing it to ground out on the frame and blow the fuse.

use the process of elimination, disconnect both headlights at the bulb and put another fuse in it and see if it blows. if the fuse blows without the headlights plugged in then its the wiring to the bulbs. if the fuse doesn't blow while the headlights aren't plugged in try plugging the lights in one at a time to see which headlight or socket is shorted. possibly corrosion at body to ground connections near the headlights, you may not see the corrosion, remove the ground wires and sand those ground wires down..
The fuel pump fuse blowing is an indication of the fuel pump wires may be shorted inside the tank. If you drop the tank and remove the module, you may find the insulation burned off some of the pump wires. Prob a good idea to take it in. If it is happening to your model, it may be a re occurring problem for that model and mechanics may have seen it before.
the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.
Have you checked the FUEL PUMP INERTIA SWITCH in the trunk? thats the last place power goes before it gets to the pump. Is the pump recieving power? if not the switch is either bad or needs to be reset.
replace the fuel pump, it is drawing to much current, this is common when the pump bearings get worn out, also make sure you replace the fuel pump connector at the fuel tank connection, it will be burnt..
relays get hot and thats normal but the fuse burning might be caused by a defective 02 sensor or oxigen sensor disconect sensors and see if keeps blowing the fuse
other cause of burning fuse might be injectors but if you had a mufler or exaust repair latetly most likelly 02 sensor is shorting
