The CP3 injection pump is the heart of the Duramax common rail fuel system, generating up to 23,000+ PSI of fuel pressure. When building a performance LB7 Duramax, the factory pump often becomes a limiting factor. This modified 85% pump ensures adequate fuel supply for substantial power increases while maintaining reliability with Industrial Injection's proven remanufacturing process.
