Ensure you have enough space to work and remove items from the bed of the truck

When installing an auxiliary fuel tank, it is important to ensure that you have a spacious and safe working environment. Accidents and injuries are more likely to occur when individuals are working in tight spaces or are unprepared for the task at hand. Therefore, before beginning the installation process, make sure you have enough space to work comfortably and safely.

The first step is to remove any items from the bed of the truck that might hinder your work. This includes items such as a bed mat or any other objects that may be present. By clearing the space, you reduce the risk of accidents and create a more efficient working environment. It is also advisable to have an extra set of hands to help lift the auxiliary fuel tank. Not only will this make the task easier, but it will also help prevent any scrapes or scratches to the truck's finish.

Once the bed of the truck is cleared, you can begin the process of determining the placement of the auxiliary fuel tank. It is important to install the tank away from the sides, front, and back of the bed, leaving some space on all four sides of the tank. This spacing prevents the tank from rubbing against the truck bed, which could potentially cause damage to the tank.

After determining the optimal location, use a brightly coloured marking tool, such as a wax pen or chalk, to visibly mark the holes where the fuel tank will be attached to the bed of the pickup. This marking ensures that you drill the correct holes and avoids any mistakes that could damage the vehicle. It is also crucial to check the undercarriage of the truck bed to ensure that there are no other components, such as the existing fuel tank, that could be accidentally drilled.

By following these steps and ensuring you have enough space to work, you can safely and effectively install an auxiliary fuel tank in your truck.

Consider a gravity feed system over a pump

When adding an auxiliary fuel tank, it is worth considering a gravity feed system over a pump. There are several reasons why this might be preferable. Firstly, it is a more straightforward process, requiring only one fuel line and two wires for the solenoid. This simplicity also reduces the likelihood of malfunctions.

A gravity feed system can also be a more cost-effective option, as it doesn't require the purchase and installation of a pump. This can be a significant saving, especially when compared to more expensive pump systems that claim to be safer.

Another advantage of a gravity feed system is that it allows for the filtration of fuel. By running the fuel through an auxiliary tank first, you can ensure that the fuel entering your main tank is cleaner, which helps keep the factory fuel filter in better condition. This process also ensures that the engine never receives bad fuel.

Additionally, gravity feed systems can be useful when dealing with fuel tanks that have vents to the atmosphere, as they can help prevent overfilling and potential spillage.

However, it is important to note that some consider gravity feed systems unsafe, claiming they can leak. Therefore, it is essential to carefully consider your specific use case and requirements before deciding on a gravity feed system over a pump for your auxiliary fuel tank.

Mark the holes where you will install the tank on the truck bed

When installing an auxiliary diesel fuel tank, it is important to ensure that you have enough space to work and that you have removed any items inside the bed of the truck that might get in the way. Place the auxiliary diesel fuel tank in the location where it will be installed.

Before you start drilling holes in your truck bed, you need to mark the holes where you will install the tank. Your tank should come with mounting tabs, which will be located on the bottom edges, and possibly on the back edges for taller tanks. With the tank in the correct position, you can then mark the holes where you will attach the tank to the bed of your truck. It is important to use a brightly coloured marking tool, such as a wax pen or chalk, so that you can clearly see the marks and don't accidentally drill in the wrong place.

After you have marked the mounting locations, you can remove the tank from the truck bed. You should then centre punch the locations of the holes to prevent the drill bit from straying. Start by drilling pilot holes with a small bit, before drilling the final holes with a bit that matches the bolts you plan to use. Before you start drilling, check the undercarriage of the truck bed to ensure that there are no important components that might be damaged by drilling.

Use a brightly coloured marking tool to avoid drilling the wrong hole

When installing an auxiliary diesel fuel tank, it is important to take the necessary steps to ensure the process is done correctly and safely. Before you start drilling holes in your pickup bed, you must first determine the placement of the auxiliary diesel fuel tank. It is recommended to install the tank with some space on all four sides to prevent it from rubbing against the truck bed, which could potentially damage the tank. Once you have found the ideal location, use a brightly coloured marking tool, such as a wax pen or chalk, to visibly mark the holes where you will attach the fuel tank to the bed of your pickup.

Using a brightly coloured marking tool is an important step to avoid drilling the wrong hole. By clearly marking the holes with a colour that stands out, you reduce the risk of accidentally drilling in the wrong place. This step helps to ensure the accuracy and precision of your drilling, which is crucial for the safe and secure installation of the auxiliary fuel tank. Drilling in the wrong location can have serious consequences, potentially damaging the existing fuel tank or other important components of your vehicle.

When marking the holes, it is important to be precise and accurate. Take your time to carefully mark each hole to ensure that your drilling is precise. This will also help to prevent any damage to the vehicle and ensure a secure installation. It is also recommended to centre punch the locations of the holes after marking. This additional step helps to prevent the drill bit from straying away from the desired location, further reducing the risk of errors.

Determine how and where you will run the fuel supply line from the tank to the factory tank

When adding an auxiliary fuel tank, there are several factors to consider when determining how and where to run the fuel supply line from the new tank to the factory tank.

Firstly, it is important to assess the space available and ensure there is sufficient clearance around the auxiliary tank. This includes marking the mounting locations and drilling holes to secure the tank in place. The fuel supply line should be routed away from the sides, front, and back of the bed to prevent the tank from rubbing against the truck bed and causing potential damage.

Secondly, decide on the method of fuel transfer between the tanks. One option is to use a gravity feed system, where the fuel flows from the auxiliary tank to the factory tank via a manual valve. This method is favoured by some due to its simplicity and lack of electrical or mechanical components that could fail. Alternatively, a pump-based system can be used, where a separate fuel pump transfers fuel from the auxiliary tank to the factory tank through an inlet tube. This method may require additional components such as a switch on the dashboard to control the fuel transfer.

Thirdly, consider the routing of the fuel supply line to ensure it does not interfere with other components. The supply line should be securely fastened and protected to prevent damage and fuel leaks. It is crucial to check the undercarriage of the vehicle to avoid drilling into the existing fuel tank or other important components.

Finally, comply with local laws and regulations regarding auxiliary fuel tanks. Some states have specific requirements for gravity-fed fuel systems, so it is essential to research and understand the applicable regulations before installing the auxiliary tank and fuel supply line.
