Most modern fuel injected vehicles run a fuel pump in the tank and run much more fuel than it is needed to the fuel rail. A regulator keeps a certain amount of fuel pressure in the rail and then sends the rest back to the tank. However, tuners upgrade the air intake system as well as the exhaust system and often neglect that more fuel is needed to make those mods perform at their full potential. This Fuel Pressure Regulator is adjustable so you can tune the fuel pressure to your needs. <br>Features: <br>Adjustable Fuel Pressure Regulator with 1:1 Ratio. <br>Made of CNC Machined Light Weight Aluminum Material. <br>Adjustable from 0 psi to 160 Maximum Fuel Pump Capacity. <br>Readings Range from 0-8 KG/CM2. <br>Comes with Bolts, Connectors and Installation Kits. <br>Delivers Vehicles' Highest Performance, with Long Life and Highly Reliable Operation. <br>Oil-Filled Design Fuel Pressure Gauge for Maximum and Consistent Measurement. <br>Improves Fuel Delivery Efficiency and Prevents Fuel Starvation for More Consistent Boost and Fuel Flow. <br>Designed to Maintain the Optimal Fuel Rail Pressure for High Performance/ Turbocharged Engine. <br>Specification: <br>Condition: 100% new <br>Material: Aluminium <br>Color: Black, Silver, Red, Blue, Purple (Optional) <br>Connector Height: 9.5cm / 3.7in <br>Package Weight: Approx. 276g / 9.7oz <br>Fitment: Universal <br>Package Included: <br>1 * Fuel Pressure Regulator <br>1 * Black Connector <br>4 * Bolt <br>1 * Fuel Gauge <br>Note: <br>1.
