Gedlex 1-5 PSI Carb Fuel Pressure Regulator Kit – Universal Adjustable FPR for Carburetor Engines

Overview and intended use

The Gedlex 1-5 PSI Carb Fuel Pressure Regulator Kit is a universal, adjustable fuel pressure regulator designed to work with carbureted engines and facet-style fuel pumps. It helps maintain a steady pressure as fuel travels from the pump to the carburetor, supporting a more consistent spray pattern and smoother transitions between idle and driving conditions. The compact, inline design fits many engine bays and is built to endure typical workshop use while you experiment with fuel delivery settings.

Dial-in precision with a 5-stage range

The centerpiece is a top-mounted graduated knob that provides 5 discrete steps, letting you tune the outlet pressure from 1 PSI to 5 PSI. This is useful when different carburetor calibrations, fuel lines, or engine states require small pressure tweaks. For safety, keep the incoming fuel pressure under the 8 PSI limit.

Fittings, compatibility, and installation tips

Included are the common hose sizes 1/4", 5/16", and 3/8" to accommodate a variety of carb connections. For a leak-free seal, apply thread seal tape to the regulator fittings before assembly and tighten fittings according to standard torque guidelines. This helps maintain consistent pressure and reduces maintenance calls.

Durability and design

The regulator body is crafted from zinc alloy and finished with anodizing, delivering corrosion resistance and long service life. The unit's streamlined shape supports easy mounting in tight engine compartments, and the universal fit reduces the need to modify other components during installation.
