Take the guesswork out of your van’s range. The Mid City Engineering Fuel Capacity Recalibration Tool seamlessly integrates inline with the EIS system on 2019-2025 Mercedes Sprinter vans to recalibrate your Distance-to-Empty (DTE) accuracy, especially after upgrading to extended fuel tanks (40–47 gal). It also retrofits the J51 module where absent—meaning precise fuel gauge readings on long distance adventures, overland explorations, and full-built Sprinter conversions.
