The Tork Teknology OFV020 Adjustable Overflow Valve eliminates all the overflow valve problems in your 94-98 Dodge 5.9L Cummins. The stock Bosch valves are known to lose spring force causing a loss in fuel pressure resulting in decreased performance. While the Bosch unit can idle at 15-18 PSI, the Tork Teknology Overflow Valve will show 25-26 PSI! This will result in better off-idle power and a smoother idle.

This durable plated, corrosion-proof valve is assembled with a chrome ball, high tensile spring and buna seal, the OFV020 is designed for use with bio-diesel, WVO and diesel fuel. Most will install this valve if they plan on using non-standard fuels in the future. Use this valve on a stock Cummins fuel system that has a stock lift pump. This valve is not for use with Airdog or FASS Pumps.

The TORK TEKNOLOGY OFV020 ADJUSTABLE OVERFLOW VALVE is used to replace a worn-out overflow valve. With the valve having the ability to be adjusted most see the best result when the valve is adjusted to 25-26 psi. This will result in better low end power and a smoother idle.
