What You'll Learn
Fuel line size: 3/8 or 5/16?
The fuel line size for your 1969 Ford F100 depends on the specific engine and fuel system configuration of your vehicle. Some Ford F100 models may use a 3/8" fuel line, while others may use a 5/16" fuel line.
It's important to note that the fuel line size is typically determined by the inner diameter (ID) of the tubing, not the outer diameter (OD). The inner diameter is the measurement of the opening on the inside of the tube, while the outer diameter is the measurement of the entire circle of the tube, including the wall thickness.
To determine the correct fuel line size for your 1969 Ford F100, you can refer to the vehicle's factory specifications or consult a mechanic or Ford dealer. Additionally, you can visually inspect the fuel line and compare it to the dimensions of a 3/8" or 5/16" fuel line.
Another method to identify the fuel line size is to use a combination wrench or an open-end wrench. Place the wrench over the fuel line tube, and whichever size wrench fits snugly without any gap will indicate the size of the fuel line. This method ensures that the outer diameter of the fuel line matches the size of the wrench.
It's important to use the correct fuel line size to ensure proper fuel flow and engine performance. Using a fuel line that is too small can restrict fuel flow, while a fuel line that is too large can lead to leaks or improper fuel delivery.

Rubber or metal hose?
When it comes to fuel lines for your 1969 Ford F100, you might be wondering whether to go with rubber or metal hoses. Both materials have their advantages and are used in different sections of the fuel line system. Here's a detailed breakdown to help you make an informed decision:
Rubber Hose:
Rubber hoses are commonly used in fuel line systems and offer several benefits. They provide flexibility, which is crucial when connecting different components of the fuel line. This flexibility reduces strain on connections and allows for easier installation and maintenance. Rubber hoses are also known for their sealing capabilities, ensuring a tight and secure fit that prevents fuel leaks. They are generally affordable and widely available, making them a cost-effective option for fuel line systems.
Metal Hose:
Metal hoses, on the other hand, offer durability and strength. They are often used in high-pressure areas of the fuel line system, providing structural integrity and resistance to punctures or tears. Metal hoses are ideal for areas that may experience impact or abrasion, as they can withstand harsh conditions without compromising the flow of fuel. Metal hoses are also known for their heat dissipation properties, which can be advantageous in certain engine environments.
Combining Both:
In a fuel line system, it's common to use a combination of both rubber and metal hoses. Rubber hoses are typically used for connections between the fuel tank and the fuel pump, as well as from the pump to the engine or carburetor. Metal hoses are often employed in areas where the fuel line needs to be routed along the vehicle's frame, providing stability and protection. By using both types of hoses in conjunction, you can benefit from the unique advantages of each material.
Size Considerations:
It's important to note that the size of the fuel lines is also a critical factor. Common sizes mentioned for fuel lines include 3/8" and 5/16". Selecting the appropriate size ensures optimal fuel flow and performance. It's always recommended to refer to manufacturer guidelines or seek advice from Ford F100 enthusiasts or mechanics to ensure you choose the correct size and type of fuel line for your specific vehicle.

Hose kits for fuel supply
The fuel lines in your Ford F-100 play a crucial role in safely transporting gas from the tank to the engine. Over time, these fuel lines can deteriorate and cause leaks, so it's important to inspect them regularly and replace them if necessary.
When it comes to hose kits for fuel supply, there are a few options available for the Ford F-100, especially for the 1972 model. High-quality Edelbrock small block and big block Chevrolet fuel line kits offer a clean and precise fuel supply line for mechanical fuel pumps with a 3/8" NPT outlet when used with Edelbrock™ Single-Feed or Dual-Feed fuel inlet kits. These hose kits provide a direct connection from the fuel pump to the engine, ensuring a reliable fuel supply.
Additionally, Holley EFI returnless fuel system kits are also available for the Ford F-100. These kits include a Holley prefilter, fittings, and fuel hoses, providing a comprehensive solution for the fuel supply system. The specific kit without a pump is suitable for most vehicles and offers a convenient way to upgrade the fuel delivery system.
For older Ford F-100 models, such as the 1948-1952 F-Series F1, F2, F3, and F4, as well as the 1953-1972 F100, F250, and F350 Trucks, reproduction fuel tank filler hoses are available. These neoprene hoses connect the gas tank to the filler pipe, ensuring a secure fuel supply line.
When considering hose kits for fuel supply, it's important to consult experts or mechanics familiar with your specific Ford F-100 model. They can guide you in selecting the appropriate hose kit and ensuring a proper installation that complies with safety standards.

Fuel filter placement
The fuel filter on a 1969 Ford F100 is located in a canister attached to the fuel pump. The fuel filter should be placed between the tank and the electric fuel pump, with another before the carb if you are running a stock fuel pump.
The fuel lines, or fuel hoses, safely transport gas from the tank to the engine. One fuel line travels from the gas tank to the fuel pump, and another line carries the gas to either the carburetor or the fuel injectors before eventually entering the engine itself.
The fuel filter is a crucial component of the fuel system, ensuring that contaminants and debris are removed from the fuel before it reaches the engine. It is important to regularly check and replace the fuel filter to maintain optimal engine performance and prevent damage.
When replacing the fuel filter, it is important to take the necessary precautions to avoid damage to the canister and the fuel pump. One common issue is the difficulty in removing the canister, which can often be solved using a strap wrench. However, this method may cause the canister to twist and split open, so it should be done carefully.
Additionally, when replacing the neoprene rubber fuel filter gasket, it is recommended to apply a fine film of grease to prevent hardening over time.
