Wehrli Custom Fab CP3 Block Off Plate 01-16 GM 6.6L Duramax
Complete your Duramax fuel system upgrade with the WCFab Duramax CP3 Block Off Plate. Designed for GM 6.6L Duramax diesel engines, this billet aluminum plate seals the factory valley CP3 pump location when the original pump is removed for a CP3 relocation, dual fueler setup, or CP3 conversion build.
Precision CNC-machined from high-quality billet aluminum, this block off plate provides a secure and leak-free seal while maintaining a clean, professional engine bay appearance. The durable black anodized finish with engraved logo resists corrosion and matches other aftermarket diesel performance components under the hood.
Essential for CP3 Conversion Builds
When upgrading or relocating the factory CP3 fuel pump, the original valley location must be properly sealed to prevent leaks and contamination. The WCFab CP3 Block Off Plate provides a precise fit to securely close this opening while protecting the fuel system and keeping the engine valley clean.
Its billet aluminum construction ensures long-term durability even in high-heat diesel engine environments, making it a reliable solution for performance builds and fuel system upgrades.
