The Spectre adjustable fuel pressure regulator provides a 1–4 PSI range for low-pressure carbureted systems and includes barb fittings sized for 3/8 inch fuel lines. It is chrome plated for appearance and intended for systems with less than 15 PSI; it is not for fuel-injected engines. Use with the appropriate Spectre gauges and adapters to manage and protect carbureted fuel delivery.
