Standard Ignition DFIP3 is a diesel exhaust fluid pump built to maintain steady DEF delivery from the tank to the injector. It is engineered for OE-level operation and uses a high-grade composite plastic housing to help resist cracking in severe weather.

• Male terminal design
• 16 blade terminals
• Composite plastic construction for cold- and heat-exposed environments
• Built to maintain constant DEF flow during vehicle operation
• Precision-manufactured for OE performance targets

Detailed Product Overview

The Standard Ignition DFIP3 is a DEF pump for diesel emission control systems that require consistent fluid transfer and stable operation. It is a direct-fit style component for 2017-2023 Ford F-250 Super Duty, 2017-2023 Ford F-350 Super Duty, and 2018-2021 Ford F-150 applications. This part number, DFIP3, is also cross-referenced with 800-65503 for the same application.

By maintaining constant flow from the DEF tank to the DEF injector, DFIP3 supports proper emission system function and helps keep the vehicle operating as intended. The 16-terminal blade connection and male terminal layout are important details for matching the original electrical interface during replacement.

Common Issues This Part Can Address

• DEF delivery loss from a worn or failing pump
• Inconsistent fluid flow to the DEF injector
• Emission system faults related to DEF pressure or supply
• Cracking or housing damage from extreme temperature exposure
• Electrical connection mismatch during DEF pump replacement

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation.
