1998.5-2002 Cummins Overflow Valve Kit (23K401)

Genuine Bosch overflow valve kit for 1998.5-2002 Dodge Ram 2500/3500 5.9L 24V Cummins. The overflow valve sits on the back of the VP44 injection pump and regulates fuel return pressure — when it weakens or sticks, you lose rail pressure, lose power, and risk hard-start or no-start conditions.

This is a direct OE Bosch replacement, kitted with new sealing washers so leaks at the banjo fitting don't bring you back for a re-repair. Standard wear item on 24V VP44 trucks alongside the lift pump.
