Valve Bypass 15psi Phantom Fits 18688/18689

The Valve Bypass 15psi Phantom Fits 18688/18689 is a precision fuel pressure regulator designed for high-performance fuel system applications. This component is engineered for builders and technicians who require reliable fuel pressure control in custom or modified fuel systems. The bypass valve maintains system integrity by venting excess fuel pressure, protecting injectors and fuel lines from over-pressurization while ensuring consistent delivery across engine load ranges.

Manufactured by Aeromotive, this Phantom-series bypass valve features a 15 psi cracking pressure setting and utilizes black anodized aluminum construction for durability and corrosion resistance. The 1/8 inch NPT male port accommodates standard fuel system plumbing, allowing straightforward integration into existing or new fuel circuits. At just 0.32 lbs, the compact design (4.95 x 2.45 x 7.1 inches) fits easily into engine bays with space constraints, while the aluminum body ensures lightweight performance without compromising strength or longevity.

This valve is ideal for EFI fuel systems, carbureted applications, and aftermarket fuel injection conversions where pressure regulation is critical. Direct compatibility with Aeromotive Phantom fuel system components (models 18688/18689) makes it a drop-in choice for those standardizing on Phantom-series architecture. Installation requires only a threaded NPT port on your fuel system rail or regulator block—a straightforward addition that enhances system safety and component longevity in street, strip, or performance applications.
