How to use an EZ Lynk to update the Distance to Empty with an S&B Tank.

EZ Lynk Auto Agent II – Fuel Tank Calibration Guide

The EZ Lynk Auto Agent II allows you to reprogram the Distance to Empty (DTE) calculation on 2011–2022 Ford Powerstroke models.

Important: No current support for GM, Dodge, or 2023+ Ford trucks.

Once the EZ Lynk is shipped, you’ll have 10 days to use the device before we charge your card on file. If your new tank isn’t installed yet, you should still recalibrate the DTE and return the unit. The fuel gauge will remain accurate, but the DTE will read incorrectly until the tank is installed.
