PDR Diesel Overflow Valve – 1994-1998 5.9L Cummins

PDR Diesel Overflow Valve eliminates all the overflow valve problems in your 1994-1998 Dodge 5.9L Cummins. The stock Bosch valves are known to lose spring force causing a loss in fuel pressure resulting in decreased performance. The PDR Diesel Overflow Valve will increase pressures and this will result in better off-idle power and a smoother idle.
