I keep blowing the Fuse for the fuel Pump. Any ideas?

There are several things that might cause the pump to draw too many amps, restricted fuel filter, restricted fuel line, defective fuel pressure regulator, defective fuel pump. I'm not saying replace all this, just do some testing.

Does the fuse blow without turning the key on, after you turn the key on, does it have to be running awhile before the fuse will blow?
