When it comes to fuel tank maintenance, one of the most important considerations is ensuring that the gasket is properly sealed to prevent leaks and seepage. Various products are available to achieve this, each with its own advantages and disadvantages. Some of the most commonly recommended products include Permatex Aviation Form-A-Gasket No. 3 Sealant, Permatex 85420 Permashield Fuel Resistant Gasket Dressing & Sealant, and Seal-All. Other options mentioned include cork gaskets, copper grease, JB Weld, and Yamabond. It is important to note that while some products may be effective in sealing gaskets, they may not be suitable for use with fuel tanks, as they may deteriorate over time when exposed to gasoline.

Cork gasket material
The binding agent in cork gasket sheets is typically made from rubber, but it can also be plastic on rare occasions. Nitrile rubber (NBR) is the best option for fuel resistance, as it retains its strength and compressibility even when exposed to fuel. Viton/FKM rubber provides similar performance but is rarely used for binding cork sheets.
Neoprene-bonded cork is another option, although it has lower fuel resistance compared to Nitrile. It can still withstand fuels to a limited degree and may be suitable in certain situations.
When using cork gasket materials in fuel tanks, it is recommended to add a gasoline-resistant sealer for enhanced performance. Sealants like Permashield, Hylomar, and JB Weld are known to be fuel resistant. Some specific products recommended by users include Permatex Ultra Copper RTV, Permatex Aviation Form-A-Gasket No. 3 Sealant, Seal-All, Yamabond, and Right Stuff by Permatex.

Yes, one alternative is to use a sheet of gasket material, which is typically fuel-resistant. Another option is to use cork, which is resistant to fuel and has been used in the past by BMW.
It is important to use a thin coat or smear of sealant around fuel tank gaskets. Too much sealant can cause problems, such as plugging passages or having balls of sealant come off inside the motor.
Yes, there are fuel-resistant silicones available that can be used to seal fuel tanks. However, these products are typically marketed as gasket sealants and may be reliant on being sandwiched between two surfaces.
It is important to choose a gasket sealer that is specifically designed for use with fuel and will not deteriorate over time. It is also important to consider the application method and ensure that the sealant is applied correctly to avoid potential issues.
