Fuel Regulator Adjustab le High Pressure 5 - 12

The Specialty Products Company Fuel Regulator Adjustable High Pressure 5-12 psi is a precision in-line fuel pressure control system designed for gasoline-powered marine engines, performance boats, and high-demand fuel injection setups. After decades on the water, serious boaters know that stable fuel pressure is the foundation of reliable engine performance—whether you're running a center console, offshore yacht, or performance rig. This adjustable regulator bridges the gap between stock fuel systems and upgraded fuel pumps that often deliver excessive pressure, protecting your injectors and ensuring consistent engine behavior in all sea states.

Built from clear anodized aluminum, the regulator maintains structural integrity in the marine corrosive environment while allowing visual inspection of internal operation. The unit features 3/8-inch NPT inlet and outlet ports, standard on most marine fuel systems, enabling straightforward in-line installation without adapter complications. The 5 to 12 psi adjustable range provides flexibility across carburetor and fuel injection platforms—lower pressures suit traditional carbureted engines while the upper range accommodates modern EFI systems. The compact footprint (3.45 x 2.65 x 4.25 inches) and minimal weight (0.66 lbs) make it easy to mount in engine bays or fuel compartments without affecting weight distribution or balance.

Boaters upgrading from stock fuel pumps or installing aftermarket components will appreciate the pressure adjustment capability, which eliminates the need for multiple regulators or system re-engineering. The clear anodized finish resists oxidation and salt spray exposure, extending service life in brackish and saltwater conditions. Installation requires basic mechanical skill and a fuel line disconnect tool; the NPT ports accept standard marine fuel hose fittings. This regulator works seamlessly with gasoline engines and supports both gravity-feed and pump-feed systems, making it ideal for restoration projects, performance builds, and reliability upgrades on vessels ranging from day boats to extended-range cruisers.
