This video goes in depth into the process for cleaning your General Motors (Isuzu) Duramax Diesel injectors. This process was performed on a 2003 LB7, however it is nearly identical for all generations (LLY, LBZ, LMM, LML, etc.). The part number for the GM Upper Intake and Injector cleaner is X66P, and I picked it up at my local GM dealer for around $20 USD.
During the video, I show the balance rates before I ran the injector cleaner through, as well as after to show the improvement the cleaner had on the injectors.
The process is straightforward, and doesn't require any special tools. The tools/supplies you will need for the job are:
5' 3/8" Fuel Line with Hose Clamp
5' 1/2" Fuel Line with Hose Clamp
1/2 Gallon Diesel Fuel
13 Oz GM Intake/Injector Cleaner
3/8" & 1/2" Fuel Line Disconnect Tool
Screwdriver for hose clamp
