5115403-6013 urea pump is developed to protect the precision fuel supply system of heavy-duty vehicles. It efficiently captures tiny particles, sludge and separated moisture mixed in diesel fuel during long-distance transportation and complex road operations. By improving fuel cleanliness, it reduces abrasion to fuel pumps and injectors, maintains steady engine power output, avoids unplanned vehicle downtime, and acts as a cost-effective aftermarket replacement part for transport fleets and machinery operators.
