bad fuel pump??

[f250dually]

So I have an early 99 p-stroke, and I blew my max fuel pump fuse. (#20 under the hood) How do you know if your fuel pump is bad? I replaced it and after about 10mins of run time, it blew again. I bought a new $160 fuel pump and would like to know for sure if its a bad fuel pump. Any ideas would be great. It also runs kinda crappy right now......

Is there any way to know for sure that the pump is bad?

What is the fuel pressure? Do the wires OHM out good?
