The Light By-Pass Spring (MP-8050-04) from Magnafuel/Magnaflow Fuel Systems is a precision-engineered fuel system component designed for builders and enthusiasts working on various fuel delivery setups. This bypass spring plays a crucial role in regulating fuel pressure in aftermarket fuel systems, making it suitable for a wide range of applications, including street machines and competition vehicles.
As a bypass spring component, it controls the cracking pressure and flow relief characteristics of your fuel regulator, allowing excess fuel to return to the tank when system pressure exceeds the calibrated threshold. The spring's tension directly affects fuel rail pressure stability, and selecting the correct rate is essential for maintaining clean idle quality and responsive throttle response.
This component is compatible with Magnafuel fuel regulators and other aftermarket fuel system architectures, ensuring minimal weight contribution (0.02 lbs) to your fuel system assembly. Builders and tuners will appreciate the importance of this spring in achieving consistent fuel pressure under varying engine demands and load conditions.
