Duramax LONG CRANK: Fuel Filter Head

I diagnose and fix a long crank time issue on my LLY Duramax. I noticed bubbles coming out of the fuel filter head, indicating an air leak. This causes air to be introduced to the fuel system. There are filter head rebuild kits, but I opted for the full assembly from GM. Thanks for watching & let me know if you have any questions!
