For optimal service life, use clean diesel, replace filters on schedule, remove water from the fuel system, and monitor smoke and fuel consumption. During installation, confirm the injector by ESN and original marking, replace seals, inspect connector tubes and fuel lines, apply the correct torque from the Cummins service manual, prime the system, and check for leaks. Preventive inspection helps address hard starting, rough idle, black smoke, power loss, and excessive return fuel before complete failure occurs.
