Fuel line disconnect tool kit
If you're looking to make a fuel line for a Chevy pickup, one of the key tools you'll need is a fuel line disconnect tool kit. This will allow you to quickly and easily disconnect the fuel line from the connector without causing any damage.
There are a variety of fuel line disconnect tool kits available on the market, such as those offered by Orion Motor Tech, Lisle, Autoplicity, JBTools, and Homestead Hardware. These tool kits typically include a range of tools that are designed to safely and efficiently disconnect fuel lines, and they cater to a wide range of vehicle makes and models.

Routing of lines
When routing the fuel lines for your Chevy pickup, there are a few key considerations to keep in mind. Firstly, it is important to ensure that the lines do not rub against anything, as this can cause leaks and damage to the lines over time. To prevent this, you can use zip ties to secure the lines and keep them in place. This is especially important if you are reusing the factory lines, as mentioned by one Chevy owner who noted the rust flaking off the cheap/unprotected steel used in their truck.
Additionally, when routing the lines, you should consider the location of the fuel filter. One suggestion is to install an inline fuel filter along the frame rail, especially for 2003 and earlier models with a return fuel system. However, it is worth noting that some users have found the built-in filter as part of the fuel pump to be ineffective. As such, you may want to consider a different filter option or even replacing the entire fuel pump if necessary.
The material of the fuel lines is also an important consideration. While some suggest using straight steel lines for most of the routing, others recommend nylon or braided lines for sections with tight bends that are hard to access. Nylon lines are known to be durable and rust-resistant, making them a good choice for certain sections of the fuel line. However, it is worth noting that some Chevy owners have expressed disappointment with the quality of certain nylon lines, mentioning that they can still be susceptible to rust over time, especially in areas with high salt usage.
Finally, when routing the lines, it is important to consider the length and bends required to reach the fuel rail. For crew cab models, the line is longer and may need to bend above the torsion bar cross member. In such cases, it is recommended to test fit the line without removing the existing one to ensure a proper fit. This will help you determine if any adjustments are needed before finalizing the installation.

Braided connections
Braided fuel lines are a common choice for vehicles, especially in high-performance applications. They offer the highest level of performance among fuel lines and are known for their heat and abrasion resistance. This makes them a suitable option for racing and motorsport events.
When considering braided fuel lines, it is important to note that they come in different materials, with stainless steel being a popular choice. Stainless steel braided fuel lines, such as those offered by McGill Motorsport, provide excellent abrasion resistance and impact protection. These lines are designed to be flexible and are available in various sizes, including 6mm, 8mm, 12mm, 14mm, and 16mm ID. They are compatible with both high-pressure fuel injection pumps and low-pressure carburettor pumps, making them versatile for different vehicle setups.
Another advantage of braided fuel lines is the availability of kits and accessories. Companies like JEGS offer braided fuel line kits, providing all the necessary components for a complete installation. These kits can include hoses, fittings, and hard lines in different sizes and materials, ensuring compatibility with a wide range of vehicles. The cost of these kits can vary, with prices averaging a few hundred to several thousand dollars, depending on the materials, size, and brand. However, individual hoses and fittings can be purchased at lower price points, starting at around $20.
When choosing braided fuel lines, it is essential to consider the specific needs of your vehicle. While braided lines offer superior performance and durability, they may not be necessary for all applications. For instance, rubber fuel lines are a more affordable option for low-pressure applications, while steel fuel lines strike a balance between durability and the ability to handle higher pressure levels. Ultimately, the right choice depends on the specific requirements of your Chevy pickup's fuel system.

Splitting the line
When installing a fuel line, you might want to consider splitting the line and installing an inline fuel filter. This is applicable for '03 and older models with a return fuel system, whereas '04 and later models with a returnless system do not require this.
To do this, you can test fit the line without removing the existing one. This will ensure that the new line fits correctly and can be bent and manoeuvred as needed. You can then remove the existing line and install the new one, splitting it to install the fuel filter.
It is also possible to buy a kit to replace the fuel line, which can be purchased for around $150 to $200, depending on the materials used. For example, a nylon fuel line kit can be purchased for a 1999-03 Chevrolet GMC Silverado Sierra V8 for $159.
If you are splitting the line, it is important to consider the materials used. While straight steel lines are recommended, nylon or braided lines can be used for tough-to-access bends. These lines are less likely to rust and can be easier to manoeuvre, but may deteriorate faster.
