Fuel Pumps, Injection Pumps and Injectors - GM Duramax LB7 - Injectors - GM Duramax LB7

We carry stock replacement and high performance injectors for the 2001 - 2004 Chevy GMC Duramax 6.6L LB7 engines. Early problems with the LB7 injectors included crankcase dilution caused by cracks that developed near the fuel inlet fitting. Bosch has fixed this problem and also made improvements to the nozzle seat retention to improve injector performance. Signs of worn injectors may include excessive smoke, rough idle or a light "miss", low power and poor fuel economy. LB7 owners can extend the life of their injectors by using Stanadyne Performance Formula with every tank of fuel. Clean fuel is very important, so changing your fuel filters at the recommended intervals is critical. Adding an aftermarket fuel filter or a FASS will also extend the life of your injectors. Our factory new and remanufactured common rail injectors each carry a 1-year warranty.
