Fuel tank lock rings and seals are essential components of any vehicle's fuel system. These parts are responsible for securing the fuel tank in place and preventing fuel leaks. The lock ring is a circular metal piece that screws onto the fuel tank and holds it in place. The seal is a rubber gasket that sits between the lock ring and the fuel tank to create a secure seal. Without these components, fuel can leak from the tank, causing potential safety hazards and damage to the vehicle. It is important to ensure that these parts are in good condition and properly installed to maintain the safety and functionality of the fuel system.
