DDP OVERFLOW DODGE 94-98 5.9L 12 VALVE OEM OVERFLOW VALVE

The DDP DDPOVERFLOW is a high-quality overflow valve upgrade designed specifically for 1998.5–2002 5.9L Cummins trucks equipped with the VP44 injection pump. This valve regulates fuel return pressure to consistent 20–22 PSI, addressing one of the most common fueling issues with VP trucks—erratic idle, low power, and hard starts due to pressure drop.

Made with precision stainless steel internals and engineered to maintain correct fuel pressures under load, this is a must-have upgrade for reliability and performance.

Vehicle Fitment

• 1998.5–2002 Dodge Ram 2500 / 3500 – 5.9L Cummins (VP44)

 Direct-fit replacement for factory overflow valve
 Not for use with Common Rail (2003+) or P-Pump (pre-1998) trucks

Features & Benefits

• Regulates return pressure at 20–22 PSI

•  Eliminates idle surges, stalling, and pressure drop

• Stainless steel internals for long-lasting durability

•  Prevents pump damage from under-fueling

• Direct bolt-on with no modifications needed

Why Upgrade?

Stock overflow valves wear over time, leading to inconsistent fuel pressure that can shorten VP44 life. The DDPOVERFLOW stabilizes fuel delivery, helps prevent injector misfires, and ensures your injection pump performs at its best—especially when paired with an upgraded lift pump.
