Description
Description
The 2GS102 is a complete fuel system rebuild kit for 2019-2021 High Output 6.7L Cummins trucks that have suffered a CP4 pump failure. When the CP4 grenades, it sends metal shavings through the high-pressure side and contaminates injectors, fuel rails, and the supply system within minutes. This kit replaces every downstream component that needs to come out — injectors, crossover tubes, fuel rail, high-pressure lines, supply hose, and the fuel filter service kit — so you can rebuild the system back to spec.
The CP4 pump itself (or a replacement CP3 conversion pump) is sold separately, so you can pick the right pump for your build — stock-spec replacement CP4, performance CP3 conversion, or race-spec CP3. If you're planning to run a Disaster Kit with the pump included, ask us about the bundled version.
HO-Only Fitment Caveat: This kit is built for the High Output 6.7L Cummins specifically. It will not fit Standard Output engines or Cab & Chassis models — those use different fuel system components.

Notes
- This kit fits 2019-2021 6.7L HO Cummins only. Standard Output and Cab & Chassis models use different fuel system components and require a different kit. If you're not sure which engine you have, send us your VIN and we'll confirm before ordering.
- The pump is not included — pick your replacement separately. If you want the bundled kit with a pump, message us.
- Custom tuning may be required if you're converting from CP4 to CP3 — talk to us before ordering if that's your plan.
