If you're looking to replace the fuel lines on your 1969 Chevy Nova, there are a few things to consider. Firstly, you'll need to decide whether to go with a pre-formed fuel line or a custom setup. Pre-formed fuel lines are designed to replace the original fuel supply line and follow the factory routing, while a custom setup will allow you to run the lines in a different location, such as along the right inner frame rail or away from the motor. Another consideration is the material of the fuel lines. Stainless steel lines are a popular choice, but you can also find kits that include rubber fuel lines and fuel line clips. Finally, you'll need to make sure you have the correct fuel line diameter for your specific engine and fuel system setup.

What You'll Learn
Fuel line routing from the fuel tank to the engine
Fuel line routing is an important aspect of any vehicle, and the 1969 Chevy Nova is no exception. The fuel line in this car runs from the fuel tank to the engine, following the factory routing. The original fuel supply line can be replaced with a preformed fuel line that is engineered from factory original lines and manufactured with precision.
For the 1969 Chevrolet Nova SS, the main fuel line is a 3/8" stainless steel line that runs from the fuel tank to the engine. This line is designed to work with factory components and includes the correct tube ends and protective wrap. It is important to note that the fuel line should be kept away from the exhaust, headers, and engine to prevent issues such as vapor lock and fuel boiling. Some owners have mentioned that their fuel lines are routed very close to the engine without any problems, but it is generally recommended to maintain a safe distance.
The fuel line typically comes up from the tank along the frame rail and then goes down to the pump on the block. From there, it is routed away from the motor and in front of the valve cover, maintaining a distance of at least 4" or more from the motor. It then connects to a metal line with an inline gauge before going up to the carb with a banjo fitting. The V8 fuel line enters the engine compartment ahead of the shock tower, just above the frame rail, and a short flex line connects it to the fuel pump.
Some owners have shared their experiences with fuel line routing in their Chevy Novas. One owner mentioned that they followed the original Six and brake line clips until they reached the trans crossmember, where they turned the gas line away and down the outside frame rail, snaking it under the battery tray hole. Another owner shared that their fuel line enters the engine bay from through the passenger side wheel well, near the fuel pump. It is important to note that exhaust pipe locations can vary, so it is crucial to ensure that the fuel line is not running too close to a heat source.

The use of fuel clip sets and hoses
When it comes to the fuel system of a 1969 Chevy Nova, it is important to ensure that the fuel lines are securely fastened and routed correctly to prevent damage and potential safety hazards. This is where fuel clip sets and hoses come into play.
Fuel clip sets are designed to secure the fuel lines in place, preventing them from moving or vibrating excessively during vehicle operation. These clips are typically made of steel or other durable materials and are available in various sizes to accommodate different fuel line diameters. For example, the 1969 Chevrolet Nova SS offers fuel line clips in 3/8" sizes, both with and without return lines. These clips ensure that the fuel lines follow the factory routing, running from the fuel tank to the engine.
Hoses, on the other hand, are flexible components that connect different parts of the fuel system, allowing for relative movement between the components and providing a path for the fuel to flow. For instance, a short piece of rubber hose is used near the back of the front clip, connecting the fuel line to the fuel pump. This rubber hose is important as it helps to absorb any movement between the subframe and the body of the car.
When replacing or upgrading the fuel lines, it is recommended to use factory original lines or CNC-manufactured replacement lines that are engineered for precision. These replacement lines often include protective wraps and are designed to work seamlessly with factory components, including the fuel clip sets and hoses.
It is worth noting that the routing of the fuel lines can vary depending on personal preferences and vehicle specifications. While some individuals choose to follow the factory location, securing the lines with factory clips, others opt to run the lines along the right inner frame rail or in other custom paths. Regardless of the chosen route, it is crucial to maintain a safe distance from heat sources, such as the exhaust, headers, or engine, to prevent issues like vapor lock.

Fuel line stops and the use of rubber hoses
The 1969 Chevrolet Nova SS has 3/8" main fuel lines. The fuel line stops about mid-passenger door and previously continued with a rubber hose. This is original to the car, as the factory put a small piece of rubber line there to absorb any movement between the subframe and the body of the car. The rubber hose is part of a two-piece line, with the other piece being a metal line.
There are a few options for routing the fuel lines in the 1969 Chevy Nova. One option is to follow the factory routing, which runs from the fuel tank to the engine. The fuel line can be held in place by factory clips. Another option is to run the fuel line along the right inner frame rail. It is important to ensure that the fuel line is not too close to any heat sources, such as the exhaust pipe, engine, or headers.
When routing the fuel line, it is recommended to maintain a clearance of at least 1-1/2" or more between the fuel line and the block/engine. The fuel line should not touch any heat sources. If the fuel line is too close to a heat source, it can cause issues such as vapor lock.
Fuel clip sets and hoses are available for most lines. It is important to note that some products may expose you to chemicals known to the state of California to cause cancer, birth defects, or other reproductive harm.

Fuel line clearance from the exhaust
When installing a fuel line on a 1969 Chevy Nova, it is important to ensure that the fuel line is not too close to the exhaust, engine, or other heat sources. Keeping a safe distance between the fuel line and these components helps prevent issues such as vapor lock and fuel boiling.
Most people run the fuel line in the factory location, held by factory clips, which is typically about 2 inches away from the exhaust. However, some people choose to run the fuel line along the right inner frame rail, which can provide more clearance from the exhaust. Exhaust pipe locations vary from car to car, so it is important to inspect the setup and ensure the fuel line is not too close to any heat sources.
Ideally, there should be at least 1.5 inches or more of clearance between the fuel line and the exhaust. Some people have reported running their fuel lines even closer to the exhaust without any issues, but it is always better to err on the side of caution to avoid potential problems.
To achieve the necessary clearance, some people have suggested running the fuel line on the outside of the frame rails, either on the passenger or driver side. This can help to avoid issues with the driveshaft and provide more space to work with. Additionally, using heat sleeves and driveshaft loops can provide extra protection for the fuel line.
Overall, when routing the fuel line on a 1969 Chevy Nova, it is crucial to maintain a safe distance from the exhaust and other heat sources. By following the factory routing or making careful adjustments, you can ensure the fuel line is installed correctly and avoid potential issues down the road.

Fuel tank return lines
The fuel line in a 1969 Chevy Nova runs from the fuel tank to the engine, following the factory routing. The original sending unit had one small fuel line coming out, and the replacement with a larger fuel line has an extra smaller line that would be the return line.
If you are installing a "stock type" gas tank, you will need a fuel sending unit with two lines (3/8" sending and 1/4" return) and the extra return line length from the regulator back to the gas tank sending unit. The return line is necessary to prevent aeration, which can cause air bubbles to enter your fuel line and create a lean condition or starvation during a high-flow pass.
There are various methods for routing the fuel line in a 1969 Chevy Nova. The factory location is along the framerail, with the fuel line held by factory clips. Alternatively, the fuel line can be run along the right inner frame rail, ensuring it is not too close to a heat source such as the exhaust pipe. Another option is to route the fuel line away from the motor and in front of the valve cover, maintaining a distance of at least 4" or more.
When replacing the fuel line, it is important to use the correct tube ends and protective wrap. Fuel clip sets and hoses are available for most lines. It is also recommended to maintain proper clearance from the exhaust to avoid issues such as vapor lock.
