The GM 12642623 is a direct fit for 2004.5-2010 GM 6.6L Duramax 6.6L.
That being said, the Fuel Filter Head Assembly can be used on LB7 applications. This requires additional fuel line and rerouting to work properly. (You will not have the ability to reconnect the filter head heater wires. This will not cause any CEL’s or issues.)
