Ford F250 SuperDuty Pickup 4x4: I have a 1999 f250 super duty

Customer Question

I have a 1999 f250 super duty with a 7.3 that I thought the fuel pump was bad but replaced it and now the #30 fuse under the dash keeps blowing. I have looked for a short and replaced the relays but still blowing and have no power to the fuel pump!
