Injector service life depends heavily on fuel cleanliness, correct filtration and proper installation. Replace fuel filters on schedule, drain water from the fuel system and avoid contaminated diesel. If metal debris is found, inspect the pump, rail, lines, injectors and return circuit. Final fitment must be confirmed by ESN, CPL, old injector number, connector type and injector appearance.
