Technical Specifications: Brand: AEM Performance Electronics Part Number (MPN): 25-302BK Product Type: Universal Adjustable Fuel Pressure Regulator (Bypass Style) Base Pressure Range: Adjustable from 20 to 120 PSI Boost Reference Rate: 1:1 Rising Rate (Manifold vacuum/boost dependent) Ports: Two (2) -6 AN ORB Inlets (9/16"-18) / One (1) -6 AN ORB Return Outlet Gauge Port: One (1) 1/8" NPT Gauge/Sensor Port Material: CNC-machined 6061-T6 Billet Aluminum (Black Anodized) Horsepower Support: Capable of supporting fuel flow for engines up to 1,000 HP. Performance & Fitment Features: Bypass/Return Style Operation: This regulator MUST be installed downstream of the fuel rail. It requires a dedicated, unobstructed return line back to the fuel tank. Blocking the return port will result in catastrophic fuel system over-pressurization and component rupture. CRITICAL THREAD WARNING (ORB vs. NPT): The main inlet and outlet ports utilize straight threads (9/16"-18) and require -6 AN ORB fittings with O-Rings to seal. DO NOT use tapered NPT fittings in the main ports. Forcing NPT fittings into the ORB ports will crack the billet aluminum body, cause massive fuel leaks, and immediately void the manufacturer's warranty. (Only the small gauge port uses 1/8" NPT). Fuel Compatibility: Officially rated by AEM for use with Gasoline. Boost-Referenced: Features a vacuum/boost port that raises fuel pressure on a 1:1 ratio with manifold boost pressure, essential for forced-induction (turbo/supercharged) applications to prevent lean conditions. Federal Emissions Compliance: Holley Emissions Code: 5 Status: This part is classified as a physical fuel management component that does not inherently alter factory emissions control equipment. It is strictly legal for sale, installation, and street use in all 50 US states, including California. No CARB Executive Order (EO) is required for the hardware. Note: Altering factory base fuel pressure without proper ECU recalibration may cause emissions test failure. Compliance is the responsibility of the owner. Disclaimer & Warranty Information: Onyx Customs FL acts exclusively as an authorized retailer of high-performance automotive components. We do not manufacture this product. Modifying pressurized fuel systems carries extreme risk. Improper installation, utilizing incorrect fittings (NPT inside ORB ports), or failing to secure the boost-reference line will result in severe fuel leaks, catastrophic engine lean-out conditions, fires, or total vehicle loss. Onyx Customs FL assumes no liability for direct or indirect damages, vehicle fires, engine rebuilds, or diagnostics costs resulting from the incorrect installation or misuse of this component. All manufacturing defects and warranty claims are strictly the responsibility of AEM Performance Electronics. We strictly mandate that all fuel system components be installed, plumbed, and tested by a certified professional mechanic.
