Permatex 59214 and Permatex 56521 are two sealants that can be used on fuel lines

Permatex 59214 is a high-temperature thread sealant that comes in a 6ml tube. It locks and seals threaded fittings and can be used on fuel fittings. It resists leakage, vibration loosening, moisture, hydraulic fluids and diesel fuels. It also lubricates threads for easy assembly and disassembly. Parts may be repositioned up to 4 hours after application.

Permatex 56521 is a high-performance thread sealant that comes in a 50ml tube. It is formulated specifically for metal, tapered pipe thread fittings, and replaces Teflon tape and pipe dopes. It cures rapidly to withstand up to 10,000 PSI and prevents galling and protects mated threaded areas from rust and corrosion. It is ideal for stainless steel fittings, oil PSI sending units, oil and coolant lines, intake manifold switches, rear axle fill plugs, and fuel fittings.

Both of these products can be used to seal fuel lines, although it is recommended to check the specific requirements of your carburetor before use.

When sealing fuel lines and fittings, it is important to use a product that is specifically designed for this purpose. Using the wrong type of sealant can result in costly repairs. It is also important to note that some fittings, such as those at the fuel bowl inlet of the carburettor, may not require any sealant at all. These fittings are either machined or flared tubing and should seal themselves.
