Kenny,
You're talking about the main 14ga wire that goes to the fuel pump relay and out to the fuel pump and no where else, right? Everything else in the system is powered from the little 3A switched feed per the schematics, and that has to be switched. Not sure how the power feed to the fuel pump can pick up anything through 18" of 0 gage cable, but I will remember this comment. If there's a problem I can cut that relay power feed and jumper it to the battery post about 12" away.
