i replace the fuel pump, ran fine for about 30 miles give or take. then while driving the thing slowly dies. i check the fuse and sure enough its blown. replace it, it blows right away. one more fuse same result. today i tried unplugging the fuel heater someone said the plug could be shorting it out. same thing blew another fuse. i am running out of ideas on what could be causing the fuse to keep blowing in the power distribution box. any help would be greatly appreciatted. thanks..
