To find it, you'll need to:
1. Check the owner's manual: This is the first and best place to look. The manual should show a diagram of the dashboard and/or other locations where switches are commonly placed.
2. Look near the instrument panel: Many Freightliners place the switch on the dash, near the other switches. It might be labeled "Fuel Tank Select," "Fuel Tank," or have a similar designation. It may be a rocker switch or a rotary dial.
3. Inspect the area around the fuel filler necks: While less common, some trucks place a selector switch near the fuel tanks themselves.
4. Check under the hood (with the engine OFF and cooled down): Some less common installations might have the switch under the hood, near the fuel system components. However, this is less likely than a dashboard location.
5. Consult a Freightliner dealer or mechanic: If you can't find it after searching thoroughly, a Freightliner service professional will know the typical locations and can quickly identify it on your specific truck.
Safety First: Always remember to turn the engine off before inspecting areas under the hood or around the fuel system.
