Because this is a calibrated fuel-system component, the pump should not be replaced until fuel supply, filters, injectors, timing, and linkage issues have been checked.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstallation should be handled by a qualified diesel fuel-injection technician. Correct pump timing, fuel-line sealing, governor linkage setup, system bleeding, and post-installation checks are critical. Inspect the fuel feed pump, filters, injection pipes, sealing washers, return\/overflow components, and throttle\/governor linkage during service.
