How Core Charges Work

This part carries a $720.00 refundable core charge, added to your order at checkout. Return your old part and we refund it to your original payment method.

What is a core?

A core is your original used part — the one this new or remanufactured unit replaces. The core charge keeps rebuildable parts in circulation and keeps prices down for everyone.

Core charge refund timeline

Based on when we receive your core:

  • 0 – 21 days100% refund
  • 22 – 60 days80% refund
  • 61 – 90 days50% refund
  • Over 90 daysNot guaranteed — at DFIS's discretion

All cores are inspected on arrival. Incomplete, damaged or non-rebuildable cores may be denied credit or receive partial credit at our discretion. Refunds are processed within 3–7 business days after inspection.

How to return your core

  1. Download the Core Return Slip and fill in your order and part information.
  2. Drain all fluids (oil, fuel, coolant) from the core.
  3. Reinstall any plugs or caps that came with the new part.
  4. Wrap the core in a plastic bag so it can't leak, then pack it — in the new part's original box if you still have it — and secure it so it can't shift.
  5. Put the completed slip inside the box.
  6. Ship via UPS, FedEx, USPS or freight for large items. Insurance is recommended on high-value cores.
  7. Email your tracking number to returns@dfispdx.com.

Important: a core refund can't be guaranteed without the completed slip inside the package and a tracking number.

Cores we can't accept

  • Severely rusted or damaged beyond reuse
  • Missing critical components
  • Not drained of fluids
  • Improperly packaged or leaking

The Reman Bosch VP44 Injection Pump (DIS20595) restores correct fuelling and timing to a 5.9L 24V Cummins that has lost its injection pump.

Fits: 2000-2002 Dodge Ram 2500 and Ram 3500 5.9L 24V Cummins High Output (245 hp) with NV5600 6-speed manual transmission

  • Bosch 0470506028 / IPVR17X High Output calibration, rated for the 245 hp engine
  • For 6-speed manual trucks only — not interchangeable with the standard-output 0470506027 / IPVR15X pump fitted to automatics and 5-speed manuals
  • Remanufactured to OEM specification and bench-tested on Bosch-calibrated equipment
  • $600 refundable core charge — return your old pump to claim it
  • Cross-references 40+ Bosch, Cummins and Mopar numbers including 0470506021, 3937670RX, 3947031RX and R5019657AD
  • Fit a healthy lift pump at the same time — low supply pressure is the most common cause of VP44 failure (DTC P0216)

Perfect for 2000-2002 HO six-speed owners replacing a failed pump, and shops that need the correct high-output calibration rather than a close-enough substitute.
