Technical Service Bulletin:

Affected vehicles: 2019+ GM 6.6L diesel trucks.

Issue : Fuel gauge drops to empty after Initial Install and during normal operation.

Explanation: GM trucks have the ability through programming and monitoring to know exactly how much fuel is in the tank, as well as fuel consumption based on miles driven and fuel economy. Any large capacity fuel tank causes the float to move slower than the computer thinks is acceptable. When the computer sees this, it will run a system check and drop the fuel gauge to empty. When the fuel level comes off full, the gauge should return to the correction position after restarting the vehicle.

Solution: Although we were told early on that trucks have fixed themselves after several tanks of fuel when following a specific process, we are no longer able to confirm this or any other permanent fix for this issue. If this is a concern for you, we recommend using an aftermarket digital monitor to confirm accurate fuel level when this occurs.
