The engine displacement of your Nova will play a significant role in determining the appropriate size of the fuel lines to ensure optimal performance and safety.

Engine displacement refers to the volume of air and fuel that can be drawn into the engine's cylinders during the intake stroke. It is measured in cubic centimeters (cc) or liters (L) and is a crucial factor in engine performance. For a 1966 Nova, the engine displacement can vary depending on the specific model and engine configuration. Typically, these engines range from 250 to 350 cubic inches (4.1 to 5.7 liters).

To choose the right fuel line diameter, you need to consider the engine's displacement and the flow rate of fuel required. Larger engines with higher displacement will demand larger fuel lines to handle the increased volume of fuel efficiently. As a general rule, the fuel line diameter should be proportional to the engine's displacement. For instance, a 350-cubic-inch engine might require a larger fuel line, perhaps 0.75 inches in diameter, compared to a smaller 250-cubic-inch engine, which could settle for a 0.5-inch diameter line.

It's important to note that the fuel line diameter should also consider the fuel pump's capabilities and the desired fuel pressure. A more powerful fuel pump might necessitate a larger fuel line to handle the increased flow rate effectively. Additionally, the length of the fuel lines should be proportional to the engine's displacement to minimize pressure drops and ensure a steady fuel supply.

In summary, when determining the fuel line size for your 1966 Nova, start by identifying the engine displacement. Then, select a fuel line diameter that is appropriate for the engine's needs, taking into account the fuel pump's capacity and desired pressure.

For instance, a high-performance fuel injection setup might demand larger fuel lines to handle increased fuel flow rates compared to a stock system.

Start by identifying the fuel injection system's specifications, including the pump's flow rate and the required fuel pressure. This information will guide you in selecting the appropriate fuel lines. For a 1966 Nova, you might consider a high-flow fuel pump, which could necessitate larger-diameter fuel lines to ensure efficient fuel delivery.

The size of the fuel lines is critical to maintaining optimal fuel pressure and flow. Smaller lines may restrict fuel flow, leading to potential performance issues. It's essential to choose lines that can accommodate the system's requirements without causing unnecessary pressure drops. Typically, fuel lines for high-performance applications are made from durable materials like stainless steel or aluminum to withstand increased fuel pressure and temperature.

When researching, look for fuel line kits specifically designed for your chosen fuel injection system. These kits often include lines of the correct size and material to ensure compatibility and optimal performance. Additionally, consider the length of the fuel lines, ensuring they are long enough to reach the fuel pump and the engine without causing unnecessary strain or interference.

Remember, the goal is to match the fuel line requirements to the fuel injection system's demands. This research will ensure that your 1966 Nova's fuel injection setup is efficient, reliable, and tailored to your performance goals. Properly sized fuel lines are a fundamental component in achieving the desired power output and overall engine performance.
