Billet Adjustable Fuel Reg. - 94-98 4.6/5.0L

The Billet Adjustable Fuel Regulator – 94-98 4.6/5.0L is an essential fuel system upgrade for Ford Mustang GT, F-150, and Cobra owners seeking reliable fuel pressure control during high-performance driving. Factory fuel regulators lack the precision and durability needed for modified engines, turbo applications, and aggressive fuel mapping. This regulator allows you to dial in exact fuel pressure, ensuring optimal injector spray patterns and preventing lean-condition detonation across the entire RPM range.

BBK Performance engineered this unit from aluminum billet for superior corrosion resistance and thermal stability under sustained boost or high-load conditions. The adjustable design uses a simple vacuum-referenced spring mechanism, allowing you to fine-tune base fuel pressure while maintaining proper compensation during acceleration and altitude changes. Unlike restrictive stock regulators, the billet construction delivers consistent flow rates needed for fuel-injected engine builds running larger injectors or modified fuel pumps. The compact design fits cleanly in engine bays without requiring extensive plumbing rework.

This regulator is ideal for enthusiasts upgrading factory fuel systems on 1994–1998 5.0L and 4.6L naturally aspirated engines, or as a foundation component for forced-induction conversions. Installation requires basic fuel line connections and vacuum hose plumbing; most builds complete the swap in under two hours. Pair this with quality fuel injectors and a quality fuel pump to maximize reliability and drivability across all load conditions. Compatible with all stock and aftermarket fuel rail designs for these generation vehicles.
