Description Ensure a leak-free installation when replacing the injectors in your LB7 Duramax with the Dynomite Diesel Basic Fuel Injector Install Kit. Because LB7 injectors are located underneath the valve covers, the replacement process requires opening up the engine and disturbing multiple high-pressure and cooling system seals. This kit provides the high-quality gaskets, O-rings, and sealants required to reassemble your engine to factory standards, preventing costly "do-overs" caused by reused or worn-out hardware. Part Number: DDPLB7KIT-BASIC Features Comprehensive "Basic" kit for LB7 injector swaps High-quality OE-style gaskets and O-rings Ensures proper sealing of fuel, oil, and coolant systems Eliminates the need to source individual seals during the job Includes 2x Lower Valve Cover Gaskets: Seals the junction between the lower cover and the cylinder head. 2x Injector Return Line Seals Kits: Critical for preventing fuel leaks into the oiling system. 2x LB7 Injector Seal Kits: Copper washers and O-rings for correct injector seating. 1x Injector Cup O-Ring Kit: Seals the stainless steel cups into the cylinder head. 1x Fuel Line Banjo Seal (FICM): 2-pack of seals for the Fuel Injection Control Module lines. 1x Upper Radiator Pipe Seal & 1x Heater Pipe Seal: Replaces seals on coolant lines moved during the install. 2x Red Threadlocker: For securing critical hardware. 1x RTV Sealant (2.8 oz): For sealing the upper valve cover and various joints. Notes Essential Upgrades: This kit covers the seals. For a complete "bulletproof" install, we highly recommend adding a new set of LB7 high-pressure fuel lines to prevent rust contamination of your new injectors. Professional Installation: Due to the complexity of the LB7 injector location, professional installation is recommended. Warranty Click Here! For additional details specific to the product warranty.
