What does the hopper tank return oil feed into?

The hopper tank's return oil feed is designed to enter at the top of the hopper. This design allows for proper circulation and ensures that the oil can flow downward to the sump, where it can be effectively utilized and circulated back into the lubrication system of the engine. By returning oil to the top of the hopper, the system maintains optimal oil levels and promotes efficient cooling and lubrication of the engine components.

The other options do not accurately reflect the purpose and operation of the hopper tank in the lubrication system, which is specifically engineered for the oil to enter from the top, facilitating effective management of oil flow and ensuring that the system functions efficiently. Proper understanding of this design is crucial for maintaining engine performance and preventing potential oil-related issues.
