Core Charge Applies - Fitment Split: Verify Body Style Before Ordering
F-250 and F-350 Pickup fitment covers 2011-2014 only. F-350, F-450, and F-550 Cab and Chassis fitment covers 2011-2016. Verify your exact year, model, and body style before ordering. A core charge applies - cores must be returned intact in original boxes with an RMA number.

The Bostech DE6302214 is a complete CP4 fuel contamination repair kit for the 2011-2014 Ford 6.7L Power Stroke F-250 and F-350 Super Duty pickups, and 2011-2016 F-350, F-450, and F-550 Cab and Chassis applications. When CP4 pump failure contaminates the fuel system - from DEF contamination, water, or running low on fuel - metal debris circulates through the entire high-pressure system, requiring full replacement. This kit includes the reman Bosch CP4 injection pump, both fuel rails, 8 reman injectors, fuel lines, and all supporting hardware. Backed by a 24-month unlimited mileage warranty.

Buy this if...

Your 2011-2014 6.7L Power Stroke F-250 or F-350 pickup (or 2011-2016 F-350 / F-450 / F-550 Cab and Chassis) experienced CP4 injection pump failure from DEF contamination, water contamination, or running low on fuel and the entire fuel system needs to be replaced
You need a complete one-box contamination repair path - reman pump, both rails, 8 reman injectors, fuel lines, and all supporting hardware with 24-month unlimited mileage warranty coverage

Do not choose this if...

Your truck is a 2011-2014 F-250 or F-350 pickup with 2015 or newer model year - verify the fitment table matches your exact year, model, and body style before ordering
You only need individual components such as a single injector or the CP4 pump alone - this kit is designed for complete fuel system contamination replacement only

Verify before ordering...

Confirm year, model, and body style match the fitment table - pickup vs cab and chassis year ranges differ
Confirm all core components are on hand to return: 8 injectors, 1 fuel pump (complete with regulator and actuator), and 2 fuel rails - all in original boxes, intact, no substitutions
Confirm OEM interchange number matches before ordering

Why the Full System Must Be Replaced

When a 6.7L Power Stroke CP4 injection pump fails from DEF contamination, water contamination, or running low on fuel, metal debris from the pump circulates through the entire high-pressure fuel system. Replacing only the pump without addressing the rails, injectors, and fuel lines risks immediate failure of the new components from residual contamination. This is why a complete fuel system replacement kit is the correct repair path - not a pump-only fix.

The DE6302214 covers the full contamination repair in one order: reman CP4 pump, both fuel rails with sensors and regulator, 8 reman injectors with hold-downs and supply lines, fuel lines, low pressure return line, fuel supply assembly, and HP pump install kit. If your 6.7L experienced a CP4 failure event and fitment matches, this is the correct kit to order.

Buyers comparing the Bostech DE6302214 vs the Alliant Power AP57000 will find the OEM interchange numbers overlap - both kits address the same Ford 6.7L fuel contamination repair application.

Avoid These Common Mistakes

Replacing Only the CP4 Pump After Contamination:
When the CP4 fails from DEF contamination, water, or running out of fuel, metal debris travels through the entire high-pressure fuel system. Replacing the pump alone without replacing the rails, injectors, and fuel lines will cause the new pump to fail again from residual contamination. A complete system replacement is required.

Ordering based on model year without confirming body style: F-250 and F-350 pickups are covered through 2014 only; F-350, F-450, and F-550 Cab and Chassis are covered through 2016 - body style determines eligibility
Returning an incomplete fuel pump core: The pump must be returned complete with the regulator and actuator - a pump missing either component will not be accepted for core credit
Returning cores without an RMA: Obtain an RMA number before shipping cores back - returns without an RMA will not be processed for credit

Before You Order

Year, model, and body style confirmed in fitment table
OEM or aftermarket part number verified against interchange list
CP4 pump confirmed complete with regulator and actuator - required for core return
All 8 injectors and both fuel rails on hand for core return - intact and in original boxes
RMA process noted - contact PDP before returning cores, customer responsible for core return shipping

For a 2011-2014 Ford 6.7L Power Stroke F-250 or F-350 pickup (or 2011-2016 F-350 / F-450 / F-550 Cab and Chassis) that experienced CP4 pump failure and requires full fuel system replacement, the Bostech DE6302214 is the correct contamination repair kit to order.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Will the Bostech DE6302214 fit my 2015 Ford F-350 Super Duty 6.7L?

It depends on the body style. The DE6302214 covers 2015 and 2016 F-350 Super Duty applications only in Cab and Chassis configuration. The F-350 Super Duty Pickup is confirmed through 2014 only. If your 2015 F-350 is a Cab and Chassis, fitment is confirmed. If it is a pickup, this kit does not apply - verify your body style before ordering.

Does the Bostech DE6302214 include the injectors?

Yes. The DE6302214 includes 8 remanufactured Bosch injectors with hold-down bolts and supply lines. It also includes the reman Bosch CP4 injection pump, both new Bosch fuel rails (with rail pressure sensor and fuel pressure regulator on the left rail), HP pump to rail fuel line, low pressure fuel return line, fuel supply assembly with sensors, and high pressure fuel pump install kit.

Why do I need to replace the whole fuel system after CP4 failure?

When a CP4 pump fails from DEF contamination, water contamination, or running low on fuel, metal debris from the pump circulates through the entire high-pressure fuel system. If only the pump is replaced without addressing the contaminated rails, injectors, and fuel lines, the debris will damage the replacement pump. A complete system replacement is required to prevent repeat failures.

What do I need to return for the core charge credit?

Three core items must be returned: all 8 injectors, the fuel pump (complete with regulator and actuator - missing either will not be accepted), and both fuel rails. All cores must be in original boxes, intact, matching units, no disassembly, no missing parts, no substitutions. An RMA number is required before returning - contact the seller to obtain your RMA before shipping.

Is the Bostech DE6302214 the same as the Alliant Power AP57000?

Both the DE6302214 and AP57000 cross-reference the same Ford OEM fuel contamination kit part numbers for the 6.7L Power Stroke. They address the same application - a complete CP4 fuel system replacement following pump failure. Verify the fitment table and OEM interchange numbers against your specific truck before ordering either kit.

What warranty does the Bostech DE6302214 come with?

The DE6302214 carries a 24-month unlimited mileage warranty against material and workmanship defects. See the warranty section for full details and applicable conditions.
