AP57015 DCR Fuel Contamination Conversion Kit - Ford 6.7L 2011-2014

The AP57015 DCR Fuel Contamination Conversion Kit is the complete high-pressure fuel system restoration path for the 2011-2014 Ford F-250 and F-350 6.7L Power Stroke, built around a CP4 to DCR pump conversion rather than a stock-style CP4 replacement. The AP57015 fits 2011-2014 F-250 and F-350 6.7L Power Stroke trucks, includes a new DCR fuel pump and eight reman OE Bosch injectors, and is engineered to restore the entire high-pressure circuit after a contamination event rather than replace a single failed part.

Full Restoration Kit or Just a Conversion?

The AP57015 is built for one job: restoring a 2011-2014 6.7L Power Stroke fuel system after CP4 contamination has already reached the injectors, rails, and lines - not for a truck that simply needs a preventative pump swap. Buy this kit if metal debris from a failed CP4 has already spread through the high-pressure circuit. Stay with a standalone CP4 to DCR conversion kit if you are converting proactively and have not had a contamination event. If your truck matches the fitment above and you are set to return the core parts, this is the correct kit to order if the fitment and contamination checks match.

6.7L Power Stroke CP4 Failure Symptoms

Owners searching "6.7 Powerstroke low fuel pressure," "metal in fuel system," or "CP4 pump failure F-250" are usually dealing with sudden power loss, hard starting, fuel pressure codes, or an unexpected shutdown. The factory CP4 pump depends on minimal internal lubrication, and once it starts wearing, metal debris moves through the high-pressure fuel circuit fast, contaminating injectors, rails, and lines in the process. The AP57015 addresses that contamination at the system level by replacing the affected injectors, rails, and lines while converting the pump itself from CP4 to DCR. More on how CP4 failures progress is covered in our CP4 failure guides.

Why Convert From CP4 To DCR

The factory CP4 pump depends on diesel fuel itself for internal lubrication, which is what allows metal debris to spread once wear begins. This kit's conversion carries OE Equivalent # 6.7F-DCR-1, the same designation used in the standalone S&S Diesel DCR pump, which is built around a two-piston eccentric drive with a pressure-lubricated cam and bushings rather than fuel-dependent lubrication, along with a corrosion-resistant fuel control actuator and materials rated for biofuel and low-lubricity fuel. It is engineered to match the factory CP4 output curve, so the stock ECU calibration runs it correctly without tuning changes.

What Comes in the Box

The AP57015 covers the full high-pressure circuit for a CP4-to-DCR conversion on 2011-2014 6.7L trucks, including new pressure and temperature sensors.

• 1x Fuel Injector Pump Conversion Kit, CP4 to DCR - OE Equivalent # 6.7F-DCR-1
• 1x New DCR Fuel Pump
• 4x Reman OE Bosch Injectors (Cyl 1/2/7/8) with hold down bolt and line
• 4x Reman OE Bosch Injectors (Cyl 3/4/5/6) with hold down bolt and line
• 1x New OE Bosch Fuel Rail, Passenger Side - OE# BC3Z-9D280-A
• 1x New OE Bosch Fuel Rail, Driver Side with Rail Pressure Sensor and Fuel Pressure Regulator - OE# BC3Z-9D280-B
• 1x Fuel Line, Rail to Rail - OE# BC3Z-9E964-A
• 1x Low Pressure Fuel Return Line - OE# BC3Z-9A564-B
• 1x Fuel Pressure Sensor
• 1x Temperature Sensor
• 1x High Pressure Fuel Pump Install Kit - PN# AP0157

New fuel pressure and temperature sensors are included, so nothing needs to be sourced separately for the high-pressure circuit replacement covered by this kit.

If your part number, fitment, and truck match the table above, this is the correct kit to review.

Avoid These Common Mistakes

• Ordering the AP57015 for an F-450 or F-550 - this kit is listed for F-250 and F-350 only.
• Ordering by engine size alone without checking model year - 2015-2016 trucks need the 15-16 contamination kit instead.
• Assuming a pump-only swap is enough after a contamination event - metal debris can reach the injectors and rails too.
• Discarding the old injectors, fuel rails, or CP4 pump before arranging core return - core credit requires those parts back.

Fitment Coverage

Fits 2011-2014 Ford F-250 and F-350 trucks with the 6.7L Power Stroke only.

Final Fit Check

• 2011-2014 F-250 or F-350 6.7L Power Stroke confirmed
• New DCR pump and fuel pressure/temperature sensors confirmed included - no separate sensor purchase required
• Contamination event (not proactive conversion only) confirmed
• Core return plan confirmed - injectors, fuel rails, and CP4 pump go back, return shipping is on you

For a 2011-2014 F-250 or F-350 6.7L Power Stroke recovering from CP4 contamination, the AP57015 is the correct full-system kit to order.
