What is the 1979 Chevy Dual Fuel Tank Wiring Diagram and How is it Used?

The 1979 Chevy Dual Fuel Tank Wiring Diagram is a technical illustration that details all the electrical connections involved in the operation of the dual fuel tank system on Chevrolet vehicles from that year. This includes the fuel pumps (often one in each tank or a single pump with a selector valve), the sending units within each tank that report the fuel level to the gauge, and the fuel selector switch located inside the cab. The primary purpose of this diagram is to show the flow of electrical current from the vehicle's power source, through the various components, and back to ground. This allows for precise identification of wires, connectors, and their corresponding functions.

Fuel Gauge Operation: The diagram clearly illustrates how the sending unit in each tank sends a variable resistance signal to the fuel gauge.
Fuel Pump Activation: It shows how the selector switch directs power to the appropriate fuel pump or activates the selector valve.
Troubleshooting Guide: Mechanics and DIYers use this diagram to systematically diagnose problems. For instance, if the gauge reads empty regardless of fuel level, the diagram helps trace the circuit from the sending unit to the gauge.

The importance of having an accurate 1979 Chevy Dual Fuel Tank Wiring Diagram cannot be overstated . It prevents guesswork, avoids accidental damage to sensitive electrical components, and ensures that repairs are made correctly the first time. Without it, attempting to repair or modify the dual fuel system can lead to significant frustration and potentially costly mistakes.
