Single Regulator Flange Plate

The Edelbrock Single Regulator Flange Plate (MPN 8189) is a precision fuel pressure regulator bracket engineered for custom fuel system installations on street, race, and modified vehicles. This plate-style mounting solution addresses a critical need for builders and mechanics: secure, repeatable positioning of fuel regulators in engine bays where factory brackets don't exist or won't accommodate aftermarket fuel delivery systems. Whether you're building a carbureted engine with mechanical fuel injection, upgrading to a modern EFI system, or customizing a vintage platform, this regulator bracket provides the structural foundation your fuel system demands.

Constructed from durable aluminum in natural finish, the Single Regulator Flange Plate features a square bore design that accommodates standard regulator mounting configurations with predictable bolt-hole patterns. The 0.3-inch thickness provides sufficient rigidity to prevent vibration-induced stress on fuel lines and regulator internals—a critical factor in high-vibration environments like dedicated race engines or turbocharged builds. At just 0.72 pounds, the lightweight design minimizes unsprung mass while its compact 7.55 x 11.5-inch profile fits tight engine compartments without requiring extensive frame or firewall modification. The natural aluminum finish allows for painting or powder coating to match your engine color scheme while maintaining corrosion resistance in underhood conditions.

Mechanics and engine builders benefit most from this bracket when fabricating fuel systems for restorations, LS swaps, carbureted conversions, and performance upgrades where OEM regulator mounts are unavailable or incompatible. Installation requires basic fasteners and positioning relative to your fuel rail or carb fuel inlet—mount it on an accessible engine bracket, firewall section, or custom frame tab using the square bore mounting points. Verify your regulator's mounting hole pattern against the plate's spacing before purchase to ensure proper fitment; this single-regulator design is ideal for carburetor applications or naturally aspirated EFI systems operating at typical 4–10 PSI fuel pressures. The Edelbrock name carries proven reliability in fuel system components, making this bracket a dependable choice for long-term durability in both street and competition environments.
