Polttoaineen ruiskutuspumppu

Please start with the part number on your existing pump and compare it with the replacement numbers on the product page. Your engine model and equipment model are also helpful, especially when a pump has several listed applications. If you are still unsure, please send us the part number and equipment details through our Request a Quote page, and we can review the information available for the replacement fuel injection pump.

A fuel injection pump supplies and meters fuel for the injection system, while a fuel injector delivers fuel into the engine according to the system's design. They perform different jobs and are not interchangeable parts. If you are troubleshooting starting problems, rough running, or power loss, please have the fuel system diagnosed before deciding which component to replace.

The condition depends on the specific product and, in some cases, the selected variant. For example, the Kubota 16032-51013 listing offers remanufactured and new aftermarket options, while the Caterpillar 436-1091 listing identifies the pump as remanufactured. Please check the product page and selected variant carefully so you know which option you are ordering.

Hard starting does not necessarily mean the replacement pump is faulty. Air in the fuel system, fuel contamination, incorrect timing, or other fuel-system issues can also contribute. Please follow the engine manufacturer's service procedures and have a qualified technician check the installation, timing, and fuel supply. Because injection systems can operate at very high pressure, do not loosen high-pressure fuel lines while the engine is running.
