Technical Service Bulletin: Effected Vehicles: 2019-to Current GM 6.6L Diesel Crew Cab Short and Long Bed Trucks Issue: Fuel gauge Drops to Empty After Initial Install and Vehicle Driven Approximately 100 Miles. Explanation: The GM trucks have the ability through programming and monitoring to know exactly how much fuel is in the fuel tank as well as fuel consumption based on miles driven and fuel economy. The design of our XXL tanks adds additional fuel volume above the OEM float which in turn will hold the float on full past what the computer thinks is acceptable. The truck will run a system check and see that the Fuel gauge is reading out of specifications and will zero the fuel gauge. This will put the truck into a semi-adaptive learning mode and the truck will start to align the specifications with the current truck parameters. In our experience 4-5 full tanks ran from Full to empty will fix this issue on analog gauges. Truck with digital gauges (such as Denali, AT4, and High Country models) can take up to 10 full tanks to remedy this issue. Recommendations: Run tank from full to empty, do not fill up until tank is close to empty.

Fitment Notes:
-Hellwig aftermarket rear sway bar #7782 is not compatible with this tank (7010320).
