where to buy · 2 retailers tracked
Fuel system parts move more fuel, or move it more reliably, than the factory setup was built to. This one is the S&S Diesel S&S 12mm High Speed Stroker CP3 Pump 2001-2010 LB7/LLY/LBZ/LMM, listed to fit the 2001-2010 Chevrolet Silverado 2500HD/3500HD.
why this one — On a diesel this is usually a reliability buy before it is a power buy. Match the pump to what the tune actually asks for. DmaxStore lists it at $2600.00, and the fitment above is what the listing itself states, not a guess.
