Can a fuel pressure regulator be fixed or adjustable?
Some regulators have a fixed pressure setting, while most aftermarket regulators are adjustable by design. Adjustable fuel pressure regulators allow the user to set the fuel pressure based on their unique combination of components and application.
Do you need a return line for a fuel regulator?
The lack of a return line helps decrease installation costs but it can also limit the performance capabilities. These regulators come in a variety of styles and typically regulate fuel pressures in the 1-9 psi range.
Where do you run the fuel regulator on a street strip?
In a street/strip application we recommend running the feed line directly to the carburetors fuel log then placing the regulator on the return line side of your fuel log. This allows the fuel to flow unrestricted to your carburetor, but still regulates the pressure and returns the unused fuel back into the gas tank.
Do you need a fuel regulator with a carburetor?
Taking the time to plan out your fuel system and matching quality components will definitely pay off in the end. Using the best aftermarket fuel pressure regulator with your carburetor ensures a safe and reliable fuel system performance for your engine. It will result in a better running, high-performance engine.
How does a non return style fuel regulator work?
Non-return style regulators are characterized by their lack of a fuel return line from the regulator back to the fuel tank. With a blocking style regulator, fuel enters through the inlet port (A), travels past the fuel control valve (B), and then is distributed through an outlet port to the carburetor.
What kind of regulator do I need for fuel pump?
It should be noted that a blocking style regulator does need an internal or external relief valve at the fuel pump, relieving bypassed fuel and pressure to the fuel tank. Multiple regulators (set at different pressures, such as with a nitrous oxide system application) may be used from one pump.
Where does fuel enter a blocking style regulator?
With a blocking style regulator, fuel enters through the inlet port (A), travels past the fuel control valve (B), and then is distributed through an outlet port to the carburetor. In this example, there are two outlet ports (C).
Which is the return or bypass style regulator?
Design. Return, or bypass, style regulators are characterized by a fuel return line from the regulator back to the fuel tank. With a bypass style regulator, fuel enters through the inlet port (A) and travels past a fuel bypass valve/fuel return line port (which governs fuel flow and pressure)…
