IRL High Speed Bypass 65-130 PSI 6AN Fittings

The IRL High Speed Bypass 65-130 PSI 6AN Fittings fuel bypass valve is engineered for high-performance fuel systems where pressure regulation and flow control are critical. This Kinsler bypass valve serves as a pressure relief component in fuel delivery circuits, protecting fuel pumps and injectors from overpressure conditions while maintaining optimal system stability. Whether you're building a custom fuel system, upgrading a performance engine, or maintaining a precision fuel setup, this bypass valve ensures safe, consistent fuel delivery across a wide operating range.

Rated for 65–130 PSI operating pressure, the IRL High Speed Bypass uses advanced internals to react rapidly to pressure spikes and maintain set-point accuracy. The valve features 6 AN inlet and outlet ports, enabling seamless integration into braided stainless steel or aluminum fuel line systems with standard automotive fittings. Constructed from aluminum and finished in gray anodize, the compact design (1.3 x 1.3 x 3.2 inches) minimizes installation footprint while delivering durable corrosion resistance and lightweight performance—critical for race cars, custom builds, and demanding fuel delivery environments.

This bypass valve is ideal for fuel system builders, racing enthusiasts, and shop technicians who demand precision pressure control without complexity. The universal design and 6 AN porting accommodate most modern fuel systems using -6 hose or hard-line plumbing. Installation is straightforward: position the valve in the return or bypass line upstream of the fuel rail, set your target pressure using the internal adjustment screw, and verify flow with a quality fuel pressure gauge. For high-speed fuel injection systems, carbureted performance engines, or any application requiring bypass protection, this Kinsler valve delivers reliable, repeatable results.
