DmaxStore CP3 Injection Pump Hose Kit 01-10 GM 6.6L Duramax LB7/LLY/LBZ/LMM

Description

Replace cracked, aging CP3 injection pump hoses before a small fuel leak turns into a bigger problem with the DmaxStore CP3 Injection Pump Hose Kit. Designed as a direct-fit replacement for the factory feed and return hoses, these pre-formed lines are an ideal upgrade when replacing a CP3 injection pump, fuel pressure regulator, or servicing the fuel system. The kits cover 2001–2004 LB7, 2004.5–2005 LLY, and 2006–2010 LBZ/LMM Duramax applications, providing the correct hose configuration for each generation without having to cut or fabricate a universal fuel hose. Built to handle the heat, fuel, and demanding conditions around the injection pump, these hoses use a 4-layer SAE 30R9 construction rated from -30°F to 257°F and compatible with diesel and biodiesel. The construction uses an FKM fluoroelastomer inner tube for chemical resistance, CSM cover material, single-braid aramid reinforcement for high-temperature stability, and an outer CSM layer for resistance to heat, ozone, and weather. Each application-specific kit includes the CP3 feed hose, CP3 return hose, and four hose clamps.

About DMAXStore

DmaxStore is dedicated to one thing: helping GMC and Chevy Duramax diesel owners get the most out of their trucks. Since 2007, DmaxStore has built its reputation around Duramax-specific parts, performance upgrades, replacement components, and technical knowledge for diesel truck enthusiasts.

Rather than trying to cover every make and model, DmaxStore focuses specifically on the Duramax platform. That specialization allows the company to carefully select products for their quality, performance, fitment, and value while providing customers with knowledgeable support when choosing parts for their trucks.

Duramax Parts From People Who Know Duramax Trucks

DmaxStore was founded after its owner spent seven years working for one of the largest GM dealers in the United States, where he earned the GM Mark of Excellence award. That experience helped establish the foundation for a business centered entirely around the GMC and Chevy Duramax diesel community.

Today, DmaxStore offers parts and upgrades covering a wide range of Duramax applications, from the original LB7 through the latest generations of the L5P, along with Duramax-powered Colorado and Canyon applications. Their product selection includes everything from maintenance and replacement parts to fuel-system upgrades, suspension components, drivetrain parts, steering upgrades, engine performance products, and more.

Performance, Replacement & Upgrade Parts

Whether you're maintaining a high-mileage Duramax, restoring an older Silverado or Sierra, or building a truck for increased performance, DmaxStore offers products designed around the needs of diesel truck owners.
