The Dorman Atomization Module ensures you are Ready for the Road Ahead™, effectively maintaining the amount of fuel that goes into the seventh injector during the DPF regeneration process. This heavy duty diesel fuel injector driver module controls the intervals for both low and high pressure fuel making this sensor an easy choice for your heavy duty needs. It is important to note when installing a new atomization module, the air dryer coalescing filter needs to be checked for maintenance and must be serviced to ensure atomization module performance. FleetPride is your First Click in Heavy Duty®.
