Installation Notes and Tips

Verify connector style, terminal count, and bolt-on mounting before installation. Inspect the mating harness, sealing surfaces, and surrounding DEF lines for contamination or damage during service. Because mounting hardware and O-ring are not included, reuse or source the required sealing and attachment components as needed for the vehicle repair.

Quality Assurance

Standard Ignition supplies emission control components for service replacement applications. Confirm fitment by year, make, and model before ordering, and match the part number DFI20 to the original component or catalog reference when servicing GM diesel emission systems.
