The Alliant Power AP57002 Fuel System Contamination Kit is designed to repair catastrophic diesel fuel system failures on 2017-2019 Ford 6.7L Powerstroke engines. This complete contamination repair kit is equivalent to Ford OE# HC3Z9B246A / HC3Z9B246B and replaces the high-pressure fuel system components commonly damaged when contamination spreads through the diesel fuel system.
If your Ford F-Series truck developed a P0087 fuel rail pressure low code, experienced low fuel supply and lack of lubrication to the CP4 pump, or had Diesel Exhaust Fluid accidentally added to the fuel tank, contamination can quickly spread through the rails, injectors, fuel lines, and pressure control components. Once that happens, replacing only one failed part often leads to repeat failure and more expensive repairs.
This kit replaces critical components including the Bosch CP4 injection pump FC3Z9A543A, fuel rails BC3Z9D280A / BC3Z9D280B, injector components associated with OE numbers FC3Z9H529A through FC3Z9H529F, and related fuel system hardware required to restore proper operation after a contamination event.

Why Full Fuel System Replacement Matters
Once contamination reaches the high-pressure side of the diesel fuel system, the damage rarely stays isolated to one part. Metal debris from a failing CP4 pump can circulate through the rails, injectors, lines, and pressure components. That is why diesel technicians often choose a complete contamination kit instead of replacing only the failed pump.
- P0087 low fuel rail pressure code
- Hard starting or no-start condition
- Injection pump failure from lack of fuel lubrication
- Visible contamination in fuel components
- Repeat failure after partial repairs
