What It Helps Address

• DEF delivery issues caused by a failing pump
• Irregular fluid flow to the DEF injector
• Emission system faults tied to low DEF pressure
• Cracking or housing damage from temperature extremes
• Replacement needs on GM diesel vehicles with LGH or LML engines

Installation Notes and Tips

Verify engine code, VIN code, port count, and terminal style before installation. The DFIP2 uses male blade terminals and a 3-port configuration, so connector and line routing should be checked against the original unit. Confirm the vehicle application against the exact year and model listing before replacing the pump. For search and catalog reference, this part number is DFIP2.
