Billet Fuel Regulator Bypass New Design

The K.S.E. Racing Billet Fuel Regulator Bypass with new design (model KSC2005) is a precision-engineered fuel pressure control system built for high-performance engines that demand adjustable, reliable fuel delivery across multiple fuel types. Constructed from aluminum and finished in black/clear anodize, this in-line regulator handles gasoline, E85, and methanol with the same consistent performance, making it essential for racers, tuners, and performance shops building engines where fuel pressure stability directly impacts combustion efficiency and power output.

The regulator features three 8 AN female O-ring ports: inlet, outlet, and return line. This configuration allows integration into fuel systems where precise pressure regulation is critical for carburetor float bowl balance, fuel injector spray pattern consistency, and overall engine response. The adjustable design lets builders dial in the exact pressure their fuel system requires, eliminating guesswork and pressure spikes that degrade performance or damage components. Compact dimensions (4.6 x 1.85 x 5.35 in) and lightweight construction (0.44 lbs) simplify installation in tight engine bays without adding significant mass or complexity to the fuel system plumbing.

This bypass regulator suits bracket racers, street performance builders, and shop technicians working on carbureted or EFI platforms where fuel pressure consistency is non-negotiable. Whether running a classic carbureted engine, a modern fuel-injected build, or an alternative fuel application, the multi-fuel compatibility and adjustable pressure range make this regulator a versatile control point in any serious fuel system. The billet aluminum construction and anodized finish resist corrosion and thermal stress from sustained high-RPM operation.
