if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing
sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

Lets see if I can help you... first I have a few questions
Have you done anything else other replace the tensioner pulley?
Did you disturb any wirirng?
I am not sure if the alternator circuit is connected to tha same fuse or not but it might be. A easy way to see if you alternator is at fault you can disconnect the main lead to the common output terminal but make sure it is taped up after disconnecting so if it does touch something it does not short out. Then try and see if the fuse still blows.
But I really dont think that it is your alternator... I suspect that your fuel pump is shorted out and this is what is causing your fuse failure.
I am about 85 percent to the fuel pump

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.

SOURCE: My 2002 f350 diesel keeps
the problem could be the fuel pump fuses only blow when they are overloaded ie. if you have a 15 amp fuse & the fuel pump or whatever is drawing 20 amps the fuse will blow,if you are using the right amp fuse the fuel pump is drawing too much power & may be faulty or there is a problem with the wiring, a loose connection or the like.....hope this helps....cheers
