Adjustable Overflow Valve

The Tork Tek OFV020 is an adjustable overflow valve specifically engineered for the Bosch P7100 injection pump found in 1994-1998 Dodge Ram 2500 and 3500 models with the 5.9L Cummins 12-valve engine. It is compatible with stock fuel systems and is built to handle alternative fuels such as Waste Vegetable Oil (WVO) and biodiesel. The OFV020 allows for precise adjustment of fuel pressure, with a preset range of 30 to 32 PSI, which can be further tuned to meet specific needs. Users have reported significant improvements, including easier starting, elimination of stalling issues, and more stable fuel pressure readings, especially under load. Installation is straightforward and typically takes only a few minutes, with clear instructions provided by Tork Tek. This upgrade is noted for its potential to resolve low fuel pressure problems and improve overall engine operation, potentially saving owners money on diagnostic and repair costs.
