  1. 100hp injectors poor fuel mileage

    01-04.5 LB7 Duramax Powertrain
    LB7, I just replaced all stock injectors at 130,000 miles because of fuel in crankcase. I replaced with Scheid Diesel Lightning 100 hp injectors, and installed a FASS lift pump with filters. Runs great, has more power, doesn't smoke much. I just pulled a trailer 500 miles empty at 74-79 mph...
