Replacing the original equipment diesel exhaust fluid (DEF) pump on certain Ford Super Duty pickup trucks equipped with Powerstroke diesel engines is an expensive proposition. When the factory pump leaks, fails to circulate DEF and causes a check engine light, installing a quality unit in its place is critical to the proper operation of the truck's selective catalytic reduction (SCR) system. A fully functioning pump is also a necessity to meet emissions standards. This DEF pump is designed to match the performance of the costly original unit and is engineered, manufactured and tested to strict standards for reliable performance and long service life. Many aftermarket DEF pumps look alike, but may include low quality components that can affect reliability and service life. This pump features Tier 1 supplier critical components and factory-spec seals to help ensure optimal performance and durability under the toughest conditions. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
