BG PMP-3240532 (OE 324-0532): function on the vehicle

Fuel Injection Pump 324-0532 | Fit for Caterpillar C4.4 is supplied by BEST GROWTH under part number PMP-3240532, cross-referenced to OE 324-0532, 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 PMP-3240532 is built to the position defined by its OE application on the platform from Caterpillar. 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.

Fitment for Caterpillar and OE cross reference

BG PMP-3240532 replaces 1 OE reference: 324-0532. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for PMP-3240532 includes Caterpillar, typically on Fit for Caterpillar C4.4 diesel engines. Coverage lists are a starting point for identification, not a substitute for checking the OE number on the vehicle.

Quote the number printed on your part with the engine code when you enquire; a single-reference part is the most common source of ordering errors when a platform received a mid-life update.
