Description

The Spelab SPFS00316 is a race fuel pressure relief valve designed as a direct replacement for the stock unit. By preventing leakage from the relief valve, it effectively reclaims lost power and increases performance at higher RPMs. This fuel rail plug is precision CNC machined from high-strength steel, ensuring durability and a perfect fitment. It addresses common issues such as low-pressure diagnostic trouble codes (DTCs) like P1093 or P0087, which can arise during power enrichment phases due to inadequate spring pressure in the stock relief valve. Drivers seeking enhanced power from their diesel engines will find this an ideal upgrade. The SPFS00316 is compatible with 2007.5-2012 Dodge Ram 6.7L Cummins diesel engines and 2004.5-2010 GM Duramax engines.
