Standard Ignition DFIP5 Diesel Exhaust Fluid (DEF) Pump

DEF Pump for Ram 3500

Standard Ignition DFIP5 is a diesel exhaust fluid pump for 2011-2012 Ram 3500 applications. It maintains steady DEF delivery from the tank to the injector so the aftertreatment system can operate with consistent pressure during vehicle use.

• Fits 2011-2012 Ram 3500
• Diesel Exhaust Fluid (DEF) pump for emission control service
• 3-port design with 10 blade terminals and male terminal gender
• Precision-manufactured internal components built to OEM specification
• High-grade composite plastic housing for resistance to cracking in harsh weather exposure
• Includes the pump assembly only

How DFIP5 Works

The Standard Ignition DFIP5 is built for diesel emission control systems that rely on stable DEF transfer to the injector. On Ram 3500 trucks, this pump helps maintain the fluid flow and pressure needed for consistent aftertreatment operation. This part cross-references Dorman - OE Solutions 599-995 for the same application.

Common Problems It Can Address

• DEF delivery loss between the tank and injector
• Low or unstable DEF pressure in the emission system
• Cracking or housing damage from weather exposure
• Driveability issues tied to DEF pump performance
• Emission system faults related to pump output inconsistency

Installation Notes

Verify connector style, terminal count, and port layout before installation. DFIP5 uses a male 10-blade terminal configuration with 3 ports, so matching the original pump connection points is important for proper fitment on 2011-2012 Ram 3500 trucks. Confirm the DEF system is clean and inspect related lines, seals, and injector components during service.

Quality Assurance

Standard Ignition builds this DEF pump with precision-manufactured internal components to meet OEM specification and support stable operating pressure. The composite housing is selected for durability in demanding weather conditions and long-term emission system service.
