Unsafe Condition
The electrical harness of the Fuel Quantity Gauging System (FQGS) is installed in the same routing as 28 Volts AC, 28 Volts DC, and 115 Volts AC electrical harnesses, which could lead to chafing and increased surface temperatures of fuel quantity probes and high level sensors inside the fuel tank, creating a potential ignition source and consequent fuel tank explosion.
