Diesel Exhaust Fluid Tank
The Diesel Exhaust Fluid (DEF) tank holds the DEF supply. The filler neck has a smaller diameter (19 mm) than the filler neck of the diesel fuel tank and is fitted with a magnetic insert so that diesel fuel cannot be mistakenly added to the DEF tank. The DEF you should use with your Detroit™ product will be API (American Petroleum Institute) certified and meet the specifications ISO 22241-1 and DIN70700. These are two widely accepted standards in use for qualifying DEF for use in exhaust aftertreatment systems. DEF (Diesel Exhaust Fluid) will be sold at over 2,500 locations throughout North America. These locations include:
- Detroit™ Distributors
- Freightliner® Truck Dealers
- Western Star® Truck Dealers
- Travel Centers of America® Truck Stops
- Petro® Stopping Centers
- Pilot Travel Centers®
- Additional Diesel Exhaust Fluid (DEF) sales locations can be found at www.afdc.energy.gov/afdc/locator/def/
If diesel fuel is added to the DEF tank or DEF is added to the diesel fuel tank, immediately contact your Certified Detroit™ Service Center for further instructions.
