Plastic fuel tank covers can trap dirt and debris, causing corrosion and damage
Plastic fuel tank covers are used to protect the tank from projectiles, rocks, and debris. However, one of their drawbacks is that they can trap dirt and debris, leading to potential corrosion and damage. This is because the plastic jacket can trap moisture and salt, causing corrosion over time. In addition, the trapped debris can cause scratches and grooves on the tank, leading to further issues.
One solution to this problem is to install an inspection plate or an inspection hatch in the plastic fuel tank. This allows for easy inspection and cleaning of the interior of the tank. By regularly inspecting and cleaning the tank, any trapped dirt and debris can be removed, reducing the risk of corrosion and damage.
Some users have shared their experiences with installing inspection plates, stating that it is a straightforward process. They recommend using a filter/funnel to clean the fuel and suggest wiping out the filter and tank with a lint-free cloth dampened with diesel to ensure all debris is removed.
Another issue related to plastic fuel tanks is ethanol damage. Some users have reported that their plastic fuel tanks have suffered from swelling and warping due to ethanol. This has led to mounting issues and, in some cases, the need for a complete replacement of the tank. To address this problem, some companies offer treatment or liner products, while others suggest using stabilising additives in the fuel to mitigate the effects of ethanol.
Overall, while plastic fuel tank covers can provide protection from external hazards, they may also trap dirt and debris, leading to corrosion and damage. Regular inspection, cleaning, and the use of appropriate treatments can help mitigate these issues and ensure the longevity of the fuel tank.

Plastic covers can protect the tank from projectiles and external damage
However, plastic covers are not without their drawbacks. Some users have reported that the plastic cover can trap moisture, salt, dirt, and debris between it and the tank, leading to corrosion and tank rot. This can cause the tank to deteriorate over time and may require replacement.
To mitigate these issues, it is important to regularly inspect and clean the area between the plastic cover and the tank. This can help to remove any debris or moisture buildup and prevent corrosion. Additionally, coating the tank with a protective layer, such as Cosmoline, can provide extra protection against corrosion.
Overall, while plastic covers can offer protection from external damage, they require proper maintenance to ensure they do not become a source of corrosion or tank rot. It is essential to weigh the benefits and drawbacks of installing a plastic cover based on the specific use case and environmental conditions.

Ethanol can damage plastic fuel tanks, causing them to swell
Plastic fuel tanks are susceptible to damage from ethanol, which can cause them to swell and, in some cases, crack and break. This is due to the ethanol's chemical attraction to water molecules, which leads to water condensation that is then absorbed by the plastic tank, resulting in warping and swelling. This issue has been commonly observed in certain motorcycle brands, such as Ducati, Harley, and MV Agusta.
The severity of the swelling can vary, with some tanks experiencing minor distortions that resolve over time, while others undergo significant expansion that interferes with mounting bolts and requires replacement. Some motorcycle manufacturers, like Ducati, have addressed this issue and made corrections. However, for older models or those without such corrections, the use of ethanol-free gasoline is recommended to prevent swelling.
There are also aftermarket treatments available to protect plastic fuel tanks from ethanol damage. These include products like Caswell coating, which is applied to the tank's interior, and fuel additives such as Startron Enzyme and K-100, which help prevent the separation of ethanol, water, and gasoline. Some companies offer alternative tank materials, such as Kevlar tanks, which are claimed to be resistant to swelling.
It is worth noting that not all plastic fuel tanks experience swelling due to ethanol. Some motorcycle brands, such as BMW, have models that are over a decade old and have not exhibited any issues with plastic tank swelling. This suggests that advancements in plastic tank design and materials may play a role in mitigating the effects of ethanol.
To summarize, ethanol can indeed damage plastic fuel tanks, causing them to swell, crack, and, in some cases, require replacement. While treatments and alternative fuel options are available to mitigate this issue, it is essential to prioritize safety and consult with experts or manufacturers before making any modifications to fuel tanks or fuel compositions.

Inspection plates can be installed in plastic fuel tanks for cleaning and inspection
Inspection plates can be installed in plastic fuel tanks to facilitate cleaning and inspection. This is a relatively easy process, and some companies even offer purpose-built inspection plates, such as the Seabuilt cover, which is said to work with poly tanks. It is also possible to fabricate a custom inspection plate.
Before installing an inspection plate, it is important to ensure that the fuel tank is mostly empty. The remaining fuel can be filtered and poured back into the tank, and fresh fuel can be added. This process helps to ensure that the tank is clean before installation.
To install an inspection plate, a hole must be cut into the plastic fuel tank. This can be done with a sharp utility knife, and it is important to ensure that the hole is cut cleanly and precisely to avoid any leaks. After cutting the hole, the next step is to drill holes for the screws that will secure the inspection plate in place. It is crucial to use the correct size and type of screws to create a tight seal and prevent leaks.
Once the inspection plate is installed, the tank should be thoroughly cleaned to remove any debris created during the installation process. This can be done using a lint-free cloth damped with diesel or other recommended cleaning solutions. It is important to ensure that all debris is removed to maintain the integrity of the fuel system.
Inspection plates provide easy access to the interior of the fuel tank, allowing for regular cleaning and maintenance. They can also be used to install additional components, such as fuel gauge senders or fuel pickup tubes. By providing a convenient access point, inspection plates make it easier to maintain the fuel tank and ensure its proper functioning.
It is important to note that any modifications to a fuel tank may void its certification. Therefore, it is crucial to carefully consider the risks and benefits before installing an inspection plate. Additionally, proper safety precautions must always be followed when working with fuel systems to avoid accidents or injuries.

Sealed fuel tanks can lead to static build-up and potential ignition
It is important to take precautions when handling petroleum products to prevent static ignition hazards. One way to reduce the risk of static build-up is to ensure that the truck is first grounded and then bonded to the receiving storage, and that the nozzle is bonded before refuelling begins. This is especially important when refuelling aircraft, as both the aircraft and the fuel truck can be subject to static accumulation due to air and tyre movement.
Additionally, it is crucial to eliminate any remaining flammable vapours before loading low-conductivity liquids. Jet nozzles, in particular, are prone to static charge build-up. When liquids are pumped through pipes at high velocities, the static charge generation can increase significantly, especially when filters are involved. Therefore, it is recommended to provide at least 30 seconds of relaxation time in the piping system before discharging the liquid.
Furthermore, small amounts of water in fuel tanks can also cause a dangerous build-up of static charges. Water washing and firefighting sprays can generate enough static charge to ignite flammable materials. It is vital to keep all petroleum products as free from water as possible to minimise the risk of static ignition. Overall, the combination of sealed fuel tanks, static build-up, and potential ignition sources can create a hazardous situation that requires careful management and adherence to safety precautions.
