1-1/2 Fuel Press. Gauge 0-15psi Liquid Filled

The 1-1/2 Fuel Press. Gauge 0-15psi Liquid Filled by Advanced Engine Design is an essential diagnostic and tuning instrument for fuel system evaluation and engine performance work. Whether you're diagnosing a carburetor stumble, verifying fuel pump output, or validating fuel pressure after a modification, this gauge delivers reliable readings under real-world operating conditions.

This liquid-filled design is engineered to dampen needle oscillation and vibration noise that plagues dry gauges on street and race vehicles. The 0-15 psi range suits carbureted engines, low-pressure EFI systems, and fuel pressure regulator testing without overspending on premium high-pressure gauges. The 1-1/2 inch dial face delivers clear, legible markings even in poor lighting or from a distance, and the all-metal construction resists corrosion and heat typical in engine bays.

Street machines, vintage hot rods, and carburetor-equipped classics benefit most from this gauge's simplicity and durability. Installation requires only a T-fitting or fuel line adapter at the pump outlet or regulator inlet; no special tools or modifications needed. The compact design fits easily into engine compartments, making it a practical choice for any automotive enthusiast.
