What You'll Learn
The benefits of installing a big line fuel kit
Installing a big line fuel kit can provide several benefits for your vehicle's performance and maintenance. Here are some advantages to consider:
First and foremost, a big line fuel kit can improve fuel flow and overall vehicle performance. By replacing the restrictive factory fuel line with a larger diameter hose, the kit allows fuel to flow more freely to the engine, resulting in improved fuel pressure readings. This can lead to better fuel efficiency and a reduction in spikes and dips, which could potentially cause engine damage. With more efficient fuel flow, you'll also have access to extremely accurate fuel pressure sensor readings directly from the fuel pressure source.
Another benefit of installing a big line fuel kit is its compatibility and ease of installation. These kits are designed for specific makes and models, ensuring a precise fit. They come with all the necessary components for installation, making the process straightforward and less time-consuming. Some kits even offer detailed instructions and technical support to guide you through the installation process.
Additionally, big line fuel kits can help address issues related to fuel supply at higher RPMs. By reducing the pressure loss associated with smaller fuel lines, a larger fuel line can improve the engine's ability to receive the required fuel supply during high-performance demands.
It's important to note that the ideal size of a fuel line depends on various factors, including engine size, horsepower, and desired performance level. Consulting a professional or conducting thorough research is recommended before making any modifications to your vehicle's fuel system.
Lastly, big line fuel kits can enhance the reliability and longevity of your vehicle's fuel system. By providing a secure and efficient connection from the fuel filter to the injection pump, these kits help optimize fuel delivery and reduce the chances of blockages or restrictions that could impact the engine's performance over time.

How to install the kit
Installing a big line fuel kit in your Cummins engine will improve your fuel pressure flow, resulting in better fuel economy and a reduced chance of engine damage. The process is relatively straightforward, and the kit comes with all the necessary components for installation.
Firstly, you will need to gain access to the injection pump inlet. This is done by removing the restrictive line from the fuel filter housing to the injection pump inlet. This will allow your vehicle’s fuel system to flow properly.
Next, you will need to replace the restrictive line with the new, larger diameter rubber hose from the kit. This hose will have a 3/8" inner diameter and be 30" long. Be sure to use the provided hose clamps to secure the hose in place.
Now, you will need to install the T-fitting. This will have a 1/8-27 NPT port and will need to be fitted to the injection pump. Again, use the provided hose clamps to secure it in place.
Finally, connect the provided 90-degree fittings and AN adapters to complete the installation.
The process should be relatively quick and easy, with some users reporting an installation time of around 30 minutes.

How to fix issues with the kit
If you encounter issues with your big line fuel kit for your 00 Cummins, there are a few things you can do to troubleshoot and resolve the problem.
Firstly, check for any leaks in the system. Leaks can occur at the fittings, hoses, or clamps. Ensure that all connections are tight and secure, and inspect the hoses for any cracks or damage. If you find any leaks, tighten the connections or replace the affected parts as needed.
Another common issue is a drop in fuel pressure, which can be caused by a clogged or dirty fuel filter. By installing the big line kit, you can help alleviate this issue as it replaces the restrictive line from the fuel filter housing to the injection pump, allowing for better fuel flow. If you haven't installed a kit yet, this could be a good option to consider.
If you have installed a big line kit and are still experiencing fuel pressure issues, check the kit's components. Ensure that the rubber hose is not kinked or blocked, and verify that the T-fitting and adapters are properly installed and compatible with your vehicle's fuel system. Refer to the installation instructions and seek support from the manufacturer if needed.
Additionally, some big line kits come with a fuel pressure sensor. If your kit includes one, make sure it is properly calibrated and connected. A faulty or incorrectly installed sensor can lead to inaccurate readings and affect the overall performance of your vehicle.
Finally, if you're unsure about the specific issue or need further assistance, don't hesitate to reach out to the kit's manufacturer or a trusted mechanic. They can provide expert guidance and help you troubleshoot any problems with your big line fuel kit.
