Detroit Diesel DD13, DD15 & DD16 CPN5 High-Pressure Fuel Pump | Bosch 0986437507 Remanufactured (A4700902150)
This is the Bosch 0986437507, a CPN5 common-rail high-pressure fuel pump remanufactured by Bosch for the Detroit Diesel DD13, DD15 and DD16. It replaces Detroit A4700902150 and A4700900850, which Detroit also sells as RA4700902150, RA4700900850 and EA4700902150, and it takes the place of the new Bosch pumps 0445020235, 0445020236, 0445020189 and 0445020190. A refundable core applies.
Low rail pressure codes, long crank times, a loss of power under load and fuel leaking from the pump are the usual reasons this pump is replaced. Check the fuel filters and the low-pressure supply first, because a restriction there shows the same symptoms. Detroit used several high-pressure pump numbers on this engine family, and Bosch remanufactures more than one of them: 0986437503 for Detroit A4720900850 on EPA07 engines, 0986437504 for A4700901550, and 0986437508 for A4720901550 on the DD15 and DD16. Read the Detroit A number or the Bosch number off your old pump before you order.
