Connecting a metal fuel line to a rubber hose is a common problem for car and vehicle enthusiasts. There are a few ways to approach this. One way is to use a double flare kit to create a bulge at the end of the tube, which can then be clamped to the rubber hose. Another method is to use a push-lock fastener with a matching hard line, which can be flared and mated to the pushlock fitting. Alternatively, you can use a combination of ferrule-type compression fittings and barbed fittings for the rubber line.

What You'll Learn
Using a pushlok fastener
First, flare the fastener, then use an AN nut and sleeve. Next, mate the fastener to the pushlock fitting. It is recommended to use fuel injection-rated hoses as regular fuel hoses are not designed to handle the pressure of fuel injection.
Some people also use fuel injection clamps to secure the connection. However, it is advised not to use worm gear clamps as they can dig into the rubber and may be unsafe.
The pushlok fastener method is a reliable way to connect metal fuel lines to rubber, ensuring a secure and safe connection. It is important to follow the steps carefully and use the appropriate tools and materials to achieve a proper connection.
Additionally, some people have mentioned using a combination of pushlok hose and JIC fittings without any issues. This method can be an alternative option for those who prefer not to deal with quick-connect fittings.

Using a double flare kit
Firstly, it is important to note that there are no compression fittings on the fuel filter; instead, there is a straight hard line and rubber hose. To begin, you will need to use a double flaring tool to create the "bubble". This can be achieved by stopping after the "bubble" is formed, without going as far as you would for a full flare. This first step will ensure that the rubber hose does not slide off the metal tube.
There are a few different tools that can be used to create this "bubble". One option is to use a regular flaring tool, which can be purchased from various retailers. Another option is to use a tool that puts a ripple in the hard line to hold the hose on. This tool can be found at http://www.irvansmith.com/. Additionally, some users have reported success with a double flare kit, performing only the first step to create the "bubble".
After creating the "bubble", you can secure the connection with clamps. It is recommended to use "fuel injection" clamps, also known as EFI clamps, instead of worm gear clamps or heater hose clamps. For added security, you can double clamp the connection with 180-degree offset EFI clamps. This will ensure that the rubber hose stays securely connected to the metal fuel line.

Clamping the rubber line
First, ensure that you have the correct type of clamps for this specific task. Fuel line clamps are similar to heater hose clamps but are designed to avoid digging into the rubber, providing a secure and safe connection. It is recommended to use two "fuel injection" clamps for a robust joint. Worm gear clamps, commonly used in other applications, are not suitable for this purpose.
When clamping the rubber line, it is essential to stretch the rubber hose over the steel line or hard line. This step ensures a tight fit and helps create a seal. You can use a little grease on the hose to aid in this process, especially if you are dealing with a high-pressure hose that may be more challenging to stretch.
After stretching the rubber line over the steel line, you can proceed to secure it with the fuel line clamps. Tighten the clamps firmly, but be cautious not to overtighten, as this may damage the rubber hose.
Additionally, consider using a flare fitting to create a more permanent connection. By flaring the end of the steel tube, you can form a "`bubble'" that provides a larger surface area for the hose and clamp to grab onto. This technique enhances the security of the connection and helps prevent the rubber line from slipping off.
Lastly, always verify that the rubber hose is appropriately rated for fuel injection or fuel-injected use. This ensures the hose can withstand the pressures and demands of fuel line applications.
By carefully following these steps and paying attention to the specific parts and tools required, you can effectively clamp the rubber line when connecting a metal fuel line to a rubber hose.

Using a compression fitting
Compression fittings are a popular method for connecting metal fuel lines to rubber hoses. This method is often used in aircraft mod shops and can provide a secure and long-lasting connection. Here is a step-by-step guide on how to use a compression fitting to connect a metal fuel line to a rubber hose:
Step 1: Prepare the Metal Fuel Line
Before you begin, ensure that the outside diameter (OD) of the metal tube is clean and free of any debris. If you are repairing a broken metal line, you may need to cut off the old fitting with a die or cut-off wheel. You can then purchase a new compression fitting that matches the size of your metal fuel line.
Step 2: Flaring the Metal Line (Optional)
Some compression fittings may require you to flare the end of the metal line. This can be done using a flaring tool, creating a bubble or a barb-like flare that will help secure the connection.
Step 3: Choose the Right Compression Fitting
Select a compression fitting that is suitable for your application. For example, a combo ferrule type compression fitting with NPT threads on one end and a barbed fitting for the rubber line can be used. Ensure that the compression fitting is the correct size and is compatible with fuel lines.
Step 4: Assemble the Compression Fitting
Follow the instructions provided with your compression fitting. Typically, you will need to thread the fitting onto the metal line, ensuring that it is tight and secure.
Step 5: Connect the Rubber Hose
Prepare the rubber hose by ensuring it is the correct size and compatible with the barbed or flared end of the compression fitting. Warming up the hose and using a small amount of grease can make it easier to stretch over the barb or flare. Push the hose firmly onto the fitting, ensuring a tight connection.
Step 6: Secure the Connection
You may use additional clamps or fittings to secure the connection further. Fuel injection clamps are often recommended over worm gear clamps for a more secure hold. Ensure that all connections are tight and secure before use.

Using a quick-connect hose
One of the challenges with this connection is that the rubber hose may not fit snugly over the steel inlet. The rubber hose may be slightly larger than the steel inlet, resulting in a sloppy fit. To address this issue, you can try warming up a low-pressure diesel fuel line and applying a small amount of grease to the hose before placing it over the barb. Alternatively, you can try to stretch the hose by pushing something larger than 3/8" inside and letting it rest for a day or two.
To make the connection, you can use a Russell 611203: EFI SAE Female Quick-Connect Hose End Fitting Straight, available from JEGS High Performance or Grainger. This fitting has a locking part that screws on, ensuring a secure connection.
Another option is to use PTC (push to connect) to AN fittings, which can be easily adapted to include an AN/BARB fitting to meet your specific needs. Various suppliers, such as summit, jegs, speedway, and earls, offer these fittings.
When using a quick-connect hose, it is essential to ensure that the fittings are properly sized and compatible with your specific application. It is always recommended to consult with a professional or refer to manufacturer guidelines for the best results.
