What should be done to the fuel tank before removing it from the engine assembly?

Before removing the fuel tank from the engine assembly, it is crucial to ensure that the tank is empty and to drain any remaining fuel if necessary. This step is important for several reasons.

First, a full or partially full fuel tank can be heavy and cumbersome, making it difficult to handle safely. Emptying the tank not only reduces its weight but also minimizes the risk of spills, which can lead to fire hazards or environmental issues if the fuel leaks out during the removal process.

Additionally, having an empty fuel tank helps in preventing fuel from leaking into the engine or surrounding areas, which is essential for maintaining safety and cleanliness in the workspace. It also facilitates a better inspection of the tank and associated components for any maintenance or repairs that may be needed after it has been removed.

Checking for leaks, inspecting the fuel lines for damage, or soaking the tank in a cleaning solution may be important steps for maintenance and safety; however, they should not be performed before ensuring that fuel is safely removed from the tank first. Therefore, ensuring the fuel tank is empty is the appropriate initial action.
