Where does the fuel go in a Duramax?
It all starts in the tank, which is where the fuel is stored whenever you fill up.

What kind of lift pump does a Duramax have?
This is true on every Duramax from the LB7 in 2001 to the LML in 2016. Interestingly enough, the 5.9 and 6.7 Cummins trucks which were equipped with an almost identical CP3 were equipped with a lift pump, and the newest L5P Duramax has one, all of which suggests a lift pump is an important part of a diesel fuel system.
What causes low fuel pressure on a Duramax?
