Fuel Pump 3417674X is supplied by BEST GROWTH under part number INJ-3417674X, cross-referenced to OE 3417674X, as a direct-fit aftermarket diesel fuel pumps. In service it sits inside the aftertreatment control loop, so its condition is judged by system behaviour — dosing, regeneration and conversion efficiency — rather than by a single measurement.

BG INJ-3417674X is built to the position defined by its OE application on the platform from Cummins. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Aftertreatment components are specified as a set. Matching the OE number is more reliable than matching appearance.
