Is Euro 2 engine using manual pump?

Euro 2 engines can use either electronic or manual fuel injection systems, but many of them are equipped with electronic pumps for improved efficiency and emissions control. Manual pumps are less common in Euro 2 engines, as the regulations aim for stricter emissions standards that electronic systems typically meet more effectively. However, some older models or specific applications may still use manual pumps. Overall, the choice depends on the specific engine design and manufacturer.
