Mr. Gasket

• The fuel pressure regulator is advantageous in the carburetor system, regulates the pressure of the fuel flowing through the system, keeps constant fuel pressure over, even during dramatic changes in fuel demand, a bypass-regulator can react more quickly to sudden changes in engine load.By plumbing a by-pass regulator style before the carburetor,drag racers can build higher pressure in the feed to help counteract the high g-forces that they experience during hard launches and rapid acceleration
• A bypass / return carb fuel pressure regulator bleeds off excess fuel pressure, dumps it into a return line, and recirculates the fuel back into the tank. This Bypass style design helps to eliminate pressure creep, lower fuel temperatures and provides a more stable pressure curve. This carb fuel pressure regulator kit lowers the load on the fuel pump also decreases the voltage it uses, makes the pump quiet and can also increase the fuel pump's life expectancy.
• Universal fit for most vehicle's Carburetor system. Adjustable pressure range: 0-15psi. You can regulate the pressure to your needs. Adjust the set screw on top to get the desired pressure. The fuel regulator pressure gauge range is 0-15psi. Provides two ORB-06 inlet/outlet ports, one ORB-06 return port and one 1/8" NPT gauge port (NPT thread requires thread sealant to seal). It does not matter the direction of flow through the inlet/outlet.
• The Mounting location of the fuel pressure regulator is depending on the application. In street - strip applications, we recommend positioning the adjustable fuel pressure regulator on the backside of the fuel log allows fuel to flow unrestricted to the carburetor but still regulates the pressure and returns the unused fuel back into your gas tank. In drag cars with rear-mounted fuel tanks that launch very hard, it may be beneficial to position the regulator before the carburetor.
• Professional installation is highly recommended. The carburetor fuel pressure regulator installation instruction included in the package. We provide after-sales service for the fuel pressure regulator kit. Any problem you have, you can contact EVIL ENERGY by Amazon message.
