Billet Fuel Regulator 5-12psi Black Top

The Billet Fuel Regulator 5-12psi Black Top by TOP STREET PERFORMANCE is a precision fuel system component engineered for street and performance applications requiring adjustable fuel pressure control. This regulator is essential for builders working with carburetor conversions, fuel injection tuning, and custom fuel system setups where OEM constraints limit performance potential.

Manufactured from billet aluminum, this regulator features a durable black anodized top and is calibrated for a 5–12 psi operating range, making it compatible with both mechanical fuel pump systems and low-pressure electric fuel pumps commonly found in street applications. The compact 3.5 x 2.5 x 4-inch footprint allows flexible mounting in tight engine compartments, while the robust billet construction ensures long-term reliability under varying fuel flow conditions.

The adjustable design allows fine-tuning of fuel delivery pressure to match your specific carburetor jetting or fuel injection mapping, preventing lean-out conditions and ensuring consistent fuel atomization across the RPM range. This regulator is ideal for hot rod builders, street performance enthusiasts, and anyone transitioning from stock fuel systems to custom setups where pressure adjustment is non-negotiable.
