Review AUTOMETER

The Autometer 4304-SPoa and 4303-SPoa are high-performance fuel pressure regulators designed for applications requiring superior fuel delivery and pressure control. These regulators are engineered to deliver precise fuel pressure to ensure optimal engine performance and efficiency.

The Autometer 4304-SPoa is a return-style fuel pressure regulator, which means it is designed to maintain a constant fuel pressure in the return line. It features a 3/8 NPT inlet and outlet and is suitable for use with fuels up to 150 psi. The regulator body is made of heavy-duty billet aluminum, anodized for durability and corrosion resistance. The internal components are made of high-strength stainless steel, ensuring long-lasting performance even under the most demanding conditions.

The Autometer 4303-SPoa, on the other hand, is a high-pressure, direct-mount fuel pressure regulator. It is designed to deliver fuel pressure to the fuel rail or high-pressure fuel system. This regulator also features a 3/8 NPT inlet and outlet and is suitable for use with fuels up to 150 psi. The regulator body is made of the same high-quality billet aluminum and stainless steel as the 4304-SPoa.

Both regulators are designed with a clear, easy-to-read, 1/8 NPT gauge port for monitoring fuel pressure. The gauge port can be used with a wide range of aftermarket fuel pressure gauges to provide real-time feedback on fuel pressure. The regulators also come with adjustable springs, allowing users to fine-tune fuel pressure to their specific engine requirements.

In summary, the Autometer 4304-SPoa and 4303-SPoa are top-of-the-line fuel pressure regulators designed for high-performance applications. They offer precise fuel pressure control, durability, and corrosion resistance. The clear gauge ports and adjustable springs make it easy to monitor and adjust fuel pressure for optimal engine performance.
