Models: 1998 (BR/BE) Ram Truck with Cummins 24 valve engine (ISB)
Note: This information applies to diesel engine applications.
With the introduction of the Cummins 24 valve electronically injected engine, a new VP44 injection pump was also introduced. The VP44 injection pump requires finer fuel filtration due to tighter tolerances within the pump.
Whenever a fuel filter is replaced, make sure the replacement filter is p/n 04883963AB
NOTE: DO NOT USE OLDER STYLE FILTERS ON THE 24 VALVE ENGINE. THE OLDER STYLE FILTER DOES NOT FILTER TO A FINE ENOUGH LEVEL FOR THE INJECTION PUMP USED ON THE 24 VALVE ENGINE.
The new style filter(p/n 04883963AB) can be used on the 1997/98 12 valve engine applications as well.
Policy: Information only.
