What is the final step in the fuel tank installation process?

The final step in the fuel tank installation process is to check for fuel leaks. This step is crucial to ensure that the installation was done correctly and that there are no leaks in the fuel system, which can lead to engine malfunction or safety hazards like fire risks. Once the fuel tank is in place and any associated components, such as fuel lines and electrical connections, are attached, it is essential to verify that everything is secure and functioning properly. Checking for leaks involves inspecting the connections and the tank itself for any signs of fuel escaping, which helps prevent potential issues during operation.

Filling the crankcase with oil, although an important task in the overall engine maintenance process, comes after ensuring that the fuel system is leak-free and ready for operation. It ensures that all systems are properly lubricated before starting the engine but is not directly related to the fuel tank installation.
