## Discrepancy

THE FUEL PUMP WIRING HARNESS IS NOT SUPPORTED WITHIN THE FUEL CELL AND CHAFED ON THE ALUMINUM FUEL LINE FROM THE PRIMARY PUMP TO THE CHECK VALVE INSIDE THE FUEL CELL.  THERE WAS .006 INCHES DAMAGE TO THE WALL OF THE FUEL LINE AND THE SHIELDING ON THE PUMP WIRING HARNESS WAS CHAFED THROUGH.  THERE WAS NO EVIDENCE OF ARCING.
