JAZ fuel cell foam is a high-quality aviation safety foam that can last up to 10 years. It is designed to prevent the concentration of fuel vapour and air mixture, reducing the risk of fire or explosion. It also helps to reduce and baffle fuel slosh, which can affect vehicle handling. While the foam is designed to last, certain factors can cause it to deteriorate prematurely. For example, the use of diesel fuel, which contains water, can cause the foam to break down, and it is recommended that the foam be replaced annually or seasonally when used with diesel. Additionally, the use of pump gas can also impact the foam's lifespan, as the ethanol in pump gas can cause the foam to deteriorate over time. Therefore, it is important to regularly inspect the foam for signs of deterioration and replace it as needed to ensure the safe and optimal performance of your vehicle.

What You'll Learn
JAZ fuel cell foam has a longer lifespan than other foams
JAZ fuel cell foam is a high-quality aviation safety foam that offers a superior lifespan, with a service life of up to 10 years or more. JAZ's foam can last up to 10 times longer than other non-fuel-approved foams on the market. This extended lifespan makes JAZ's foam a great choice for those seeking a long-lasting and reliable product.
The foam is designed to prevent the concentration of fuel vapors and air mixtures, reducing the chance of fires or explosions. Additionally, it helps to reduce and baffle fuel slosh, which can affect vehicle handling. JAZ's foam is available as a direct replacement or addition to your fuel cell and comes standard in most JAZ fuel cells.
While JAZ's foam is a durable option, it is important to note that it is not recommended for use with alcohol, methanol, ethanol, E85, or water. The water content in these fuels can cause unwanted deterioration of the foam. For gasoline and diesel fuels, however, JAZ's foam is an excellent choice and will provide extended protection and performance.
The foam will take up between 1-4% of the volume of the fuel cell and will expand when fuel is added. It is important to ensure that the foam fills between 50-75% of the fillable void to ensure optimal performance.
When it comes to replacing JAZ fuel cell foam, there is no set lifespan. However, there are some telltale signs that indicate the foam needs to be replaced. Over time, the foam will turn into granules or appear as if it has been burned. Additionally, signs of deterioration in the fuel cell or at the fuel filter are indications that the foam needs to be replaced.
In summary, JAZ fuel cell foam offers a longer lifespan than other foams on the market, providing superior protection and performance for gasoline and diesel fuels. With its ability to prevent fuel vapors and baffle fuel slosh, JAZ's foam is a reliable and safe choice for fuel cells.

The foam prevents fuel vapour and air from mixing
The foam in a fuel cell is a crucial safety feature that should not be overlooked. While it may seem like an insignificant component, the foam plays a vital role in preventing fuel vapour and air from mixing, which could lead to a potentially catastrophic explosion.
Fuel cells are a safety measure that became standard in racing vehicles after the death of Fireball Roberts from burns received during a car fire in 1964. A fuel cell is different from a fuel tank as it includes a flexible bladder that contains the fuel and is housed within a metal can. The most important part of the fuel cell is the safety foam baffling. This foam is a special, sponge-like material that is mostly air, allowing it to float on top of the fuel without reducing the capacity of the cell.
The key function of the foam is to prevent fuel vapour and air from mixing in the fuel cell. Fuel, especially volatile fuels like gasoline, gives off vapours that mix with the air in the tank. This mixture of fuel vapour and air is highly flammable and can easily explode if exposed to a spark. The foam acts as a barrier, preventing the fuel vapour and air from mixing and reducing the risk of an explosion in the event of a fire.
Over time, the foam can start to break down, especially if exposed to certain fuel types or additives. This is why it is important to regularly inspect the foam and replace it when necessary. The breakdown of the foam can cause clogging in the fuel filters, leading to potential engine issues. To check if the foam needs to be replaced, simply pinch it between your fingers. If it is brittle and breaks apart easily, it is time for a replacement.
The foam also provides other benefits, such as reducing fuel sloshing during turns, improving weight distribution and vehicle handling, and maintaining the shape of the bladder. However, its primary function of preventing fuel vapour and air from mixing is what makes it such a critical component of a fuel cell.
In summary, the foam in a fuel cell plays a vital role in maintaining the safety of the vehicle by preventing fuel vapour and air from mixing. While it may be tempting to overlook this component, doing so could have dangerous consequences. Regular inspection and maintenance of the foam are essential to ensure the continued safe operation of the vehicle.

It is not suitable for use with alcohol, methanol, or ethanol
JAZ fuel cell foam is not suitable for use with alcohol, methanol, or ethanol. The water content in these fuels can cause unwanted deterioration of the foam. The foam will turn to granules or look like it has been burnt. This deterioration can cause issues with fuel filters and fuel pumps, and can also lead to fuel starvation.
While JAZ fuel cell foam can be used with gasoline and racing fuels, it is important to note that up to 10-15% ethanol is acceptable with pump fuels. However, it is recommended to regularly check the inline fuel filters when using pump fuels with ethanol. Additionally, the use of alcohol, methanol, ethanol, or fuel additives will affect the performance of the fuel level sending unit and void any warranty.
It is worth noting that pump gas can also be hard on the foam, causing it to deteriorate over time. This is especially true for pump gas with ethanol, as the ethanol absorbs water rapidly and separates from the gasoline, taking the octane with it. Therefore, it is recommended to use ethanol-free gasoline whenever possible and to replace the foam regularly if using pump gas.
In summary, JAZ fuel cell foam is not suitable for use with alcohol, methanol, or ethanol due to the water content in these fuels causing deterioration. It is crucial to follow the recommended fuel types and regularly inspect and replace the foam to maintain the performance and safety of the fuel system.

The foam should be replaced if it looks like granules or is burnt
The foam in your JAZ fuel cell should be replaced if it has started to turn into granules or looks like it has been burnt. This is due to the water content in fuels such as diesel, alcohol, methanol, and ethanol, which will cause the foam to deteriorate over time. The foam will also need to be replaced if you notice any signs of deterioration in the fuel cell or at the inline fuel filters.
It is important to note that JAZ Products' Fuel Cell Foam is designed for gasoline and diesel fuels only. Using the foam with alcohol, methanol, ethanol, E85, or water is not recommended as these liquids can cause unwanted deterioration. Additionally, pump gas can also be hard on the foam, causing it to deteriorate over time.
To ensure the longevity of your JAZ fuel cell foam, it is recommended to replace the foam once a year or once a season if using diesel fuel. Regularly checking and maintaining the inline fuel filters going to the fuel pump is also crucial.
If you are unsure whether your JAZ fuel cell foam needs to be replaced, it is always best to consult a professional or contact JAZ Products directly for further guidance and support.
