When the injectors and fuel pump are upgraded the stock fuel pressure regulator may not be enough to suit the required pressures for the new setup. The stock FPR is preset from the factory and is non adjustable so it will limit your options. The TOMEI Fuel Pressure Regulator will ensure stable pressures are supplied with the oversized diaphragm. This special design has proven to maintain the required pressure levels with any adjustments made.
Comes with 6AN adapters and #8 nipple connectors.
