Got the assembly put it on. Instantly was leaking out of primer ball. Took it off disassembled it, there is a O-ring that is between the flange of the primer button and the male threaded part of the filter head itself that was rolled and not sealing correctly. Took the O-ring set it into the flange then pushed it on the the filter head it self with abit of grease and it sealed.

Quick change out, faster than a rebuild kit.

Having issues with loss of prime on the fuel filter housing. Replaced it with this all in one part. Easy to install! Great price and fast shipping!

Questions and Answers
Will this work with my LB7?
View Staff Answer
Answer
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.)
