Rector-Seal works well on all fittings
Rector-Seal is a good option for sealing fuel line fittings. It works well on all fittings and can help prevent leaks. Leaks can occur when fittings are over-tightened, which can stretch the threads. Rector-Seal is a better option than pipe tape, which can degrade over time and break down with fuel contact. It is important to note that some people have reported success with using braided fuel lines without any sealant, but it is generally recommended to seal the threads in some way to prevent leaks. Rector-Seal is a reliable product that can be used with confidence to seal fuel line fittings and prevent leaks.

Over-tightening fuel and hydraulic fittings can cause leaks
It is important to seal your fuel line to prevent leaks and fires. Some people use pipe tape, but it is important not to get too close to the end of the pipe threads with the tape and to clean old tape remnants out when disconnected. You can also use liquid sealant. However, over-tightening fuel and hydraulic fittings can stretch the threads, causing leaks. This is because over-tightening can ruin the fitting integrity, squeeze the rubber out of its designed position, or distort the fitting, creating gaps. Removing and reinstalling fittings can also make them prone to leaks, and some fittings are not designed to be removed and reinstalled.
