S&S Diesel Motorsport DCR Pump Conversion (2011-2026 6.7L PowerStroke)

Fitment

Built for 2011-2026 Ford trucks with the 6.7L Power Stroke, covering both the 2011-2016 engine and the 2017-and-newer engine. S&S lists it for Ford F250-F750 diesel trucks, which takes in the F-250 and F-350 Super Duty pickups, the F-450 pickup and the F-350, F-450 and F-550 chassis cabs. The S&S feature list gives the range as 2011 to 2025 while its description says 2011 to 2026, so verify fitment by VIN on a 2026 truck before you order.

One year split matters for the install: 2011-2016 models require a new vacuum pump gasket (6.7F-VAC-GASKET). Plan for it when you order. You can find the rest of the fuel system parts for your truck in our Power Stroke section. If you are not sure what engine or year you have, send us the VIN or call the shop.

Why this part

Every 6.7L Power Stroke since 2011 left the factory with a Bosch CP4.2 high-pressure pump, and the CP4 in 2011 to current Super Duty trucks has a well-earned reputation for failing without warning. The pump is lubricated by the fuel it moves. Aerated or low-lubricity fuel can let it wear and shed metal through the rails, injectors and return, and domestic diesel can fall below the lubricity the CP4 needs. The warning signs are a long crank or hard hot start, a rough idle that smooths out with rpm, sudden power loss, P0087 low rail pressure and metal in the fuel filter. It can happen at any mileage.

When the CP4 fails it rarely takes only itself. The repair covers the pump, all eight injectors, both rails and every high-pressure line, plus removing and cleaning the tank, and fuel system repairs can easily exceed $10,000. S&S points out that the CP4's reputation is backed by recalls and lawsuits leveled at several manufacturers that use it in their production vehicles.

S&S Diesel Motorsport, the common rail diesel injection specialists, teamed up with PurePower Technologies, the aftermarket division of longstanding fuel system manufacturer Stanadyne, to solve the CP4 problem on the 6.7L Super Duty. The result is a two-piston DCR pump with patented Eccentric Drive pumping technology and a pressure-lubricated cam and bushings. It is biofuel and low-lubricity fuel compatible, and it displaces 1,250 mm3 per revolution, 25% more than the CP4.2. You put it in so your daily workhorse doesn't lay down on you on the side of the road.

Frequently asked questions

Do I need a tune to run the DCR pump?

No. S&S states the conversion does not require any ECU calibration. It was not designed to add power on its own, although it has 25% more displacement than the CP4.2 if a calibration calls for it.

Should I add a CP4 Disaster Prevention Kit with it?

No. S&S says the DCR conversion is not compatible with, and does not need, its CP4 Disaster Prevention Kit. The Disaster Prevention Kit protects the fuel system from a failing CP4. The DCR replaces the CP4.

Is the DCR pump emissions compliant?

Yes. It is CARB compliant under EO# D-756-7 and SEMA certified emissions compliant (SC-SDM01-0034). It is also covered by a two-year, unlimited-mile warranty.
