- Mallory Fuel Pressure Regulators are designed for use with Mallory Electric Fuel Pumps in all-out racing applications to regulate fuel pressure between high-pressure fuel pumps and carburetors. These billet aluminum regulators (natural or anodized black) have a high-flow fuel passage so the racer isn't burdened with fuel logs or multiple fuel pressure regulators. Combined with quick-acting diaphragm assemblies, this type of regulator is the most efficient of its kind available today.
