Cummins has just released a Service/Parts topic for "New Fuel Lift Pump" for all ISB applications.
The Service/Parts topic states:
"This Service/Parts Topic announces the release on new fuel lift pumps for the ISB & QSB VP44 series engines. The new fuel lift pump, Part Number 4932707, obsolete and supersede the previous fuel lift pumps (Parts Number 3990105). The new fuel lift pump has a internal bypass circuit in the rotor housing that allows fuel to be drawn, with less restriction, from the fuel tank to the fuel injection pump in the event of an inoperable fuel lift pump. There are no visual differences between the new fuel lift pump and the old fuel lift pump. The new fuel lift pump can only be identified by the part number. "
The price of these new pumps will be close to the same price of the 3990082/3990105. The 4932707 is the liftpump out of the 4090046 kit.
