8975153011 Original Excavator 6HK1 Engine Electric Fuel Pump

Part number 8975153011 (also written as 8-97515301-1) is the original electronic fuel pump assembly (low-pressure fuel transfer pump) that Isuzu uses for the 6WG1 series diesel engine. This component is the core part of the engine fuel supply system, responsible for steadily delivering fuel from the fuel tank to the high-pressure fuel pump. Its universal model is this part number, mainly suitable for construction machinery equipment equipped with Isuzu 6WG1 engine, such as Hitachi ZX870-5G, ZX450-3, ZX470H-3, ZX500LC-3 and other models of excavators. As an original component, its flow rate, pressure, voltage (usually 12V or 24V), and installation interface are precisely matched with the engine fuel system design.

This product is an electric vane or gear fuel pump, usually integrated with a filter screen and a check valve. Its core function is to establish fuel pressure before starting the engine and continuously provide stable flow and pressure of fuel during operation, ensuring the normal operation of the high-pressure fuel pump and common rail system. As an original component, its durability, noise control, and resistance to fuel pollution all meet Isuzu's strict standards.

Inspection and replacement: When there are problems such as difficulty starting, weak acceleration, engine stalling, or insufficient fuel pressure, the electronic fuel pump should be inspected. Simple inspection method: When the key door is opened (without starting the engine), listen for a brief pump running sound near the fuel tank (about 2-3 seconds). If there is no sound or abnormal sound, the pump may be damaged. This pump is a critical component, and once a fault is confirmed, it is recommended to replace it immediately. Attention: Be sure to use clean and standard diesel fuel; When replacing the fuel filter, avoid impurities from entering the new pump; Moisture and shock resistance are required during storage. The reliability of the electronic fuel pump is directly related to whether the engine can start and operate normally. When replacing it, it is necessary to confirm that the part number matches perfectly.
