This Bosch VP44 injection pump was used in the 1998.5-2002 Dodge pickups with the 24 valve, 235 horsepower 5.9L Cummins engine. VP44 injection pump failures are most frequently caused by a faulty fuel supply pump, a plugged fuel filter, or performance modules spliced into the injection pump wiring harness. If replacing the pump becomes necessary we advise that the fuel supply pump pressures be checked and replace the fuel filter at the same time. The fuel pressure should read between 12-15 psi at idle and 9-11 psi under load driving at highway speeds. If pressures drop below 5 psi the fuel supply pump should be replaced. To monitor and prevent future injection pump failures due to low fuel pressure we offer a "low fuel pressure warning light kit". Order this injection pump if the part number stamped on the side of the original pump is one of the following: 0470506005, '011, '015, '022, or '027. To verify that this is the correct pump number for your vehicle, please include the engine serial number (located on the engine data tag on the front driver's side of the engine) when placing your order.
