It is important to regularly inspect and replace the OP relay as needed to ensure proper function of the fuel system.

In summary, the oil pump relay plays a crucial role in the operation of a vehicle's fuel system. By activating the oil pump, it ensures that fuel is delivered to the engine at the proper pressure. Regular maintenance and replacement of the OP relay can help prevent issues and ensure optimal performance of the vehicle.<
