Thumbnail Filmstrip of 6.7L Cummins Standard Output Fuel Contamination Kit - Alliant AP57019 Images
Fuel contamination on a 2021 Ram 6.7L Cummins rarely stays in one part. Once DEF, water, microbial growth, or metal debris reaches the high-pressure side, the injectors, pump, rail, and lines have all seen it, and leftover debris can wipe out a new part if you only replace the one that failed.
The Alliant Power AP57019 Fuel Contamination Kit puts the whole high-pressure system, plus the gaskets and filters you need for the job, in one box for 2021 Ram 2500 and 3500 trucks with the Standard Output engine. That means one part number to order and no chasing pieces mid-repair.
What you get:
- Six Standard Output fuel injectors
- High-pressure fuel injection pump and fuel rail
- Six injector connector tubes and seven injector fuel supply lines
- Intake connection, EGR valve, and rocker housing gaskets for the teardown
- Fuel filter and fuel filter/water separator so the repair starts clean
- Fits 2021 Ram 2500 and 3500 with the 6.7L Cummins Standard Output engine only
Specs:
- Alliant Power part number: AP57019 (Alliant item APP41435)
- Application: 2021 Ram 2500 and 3500, 6.7L Cummins Standard Output
- Injector OE equivalent: 68444791AA
- Fuel injection pump OE equivalent: 68533241AA
- Fuel rail OE equivalent: 68533289AA
- Injector connector tube OE equivalent: 68441874AA
