MRN MECH FUELPUMP GM BB 130GPH

This Holley mechanical fuel pump (part number 712-454-13) is designed for GM Big Block engines and is a high-output fuel pump. It flows 130+ GPH (gallons per hour) free flow, and the shutoff pressure is pre-set from 7.5 to 9 psi. A fuel pressure regulator is required (Holley P/N 12-704 is recommended). It features heavy-duty construction for continuous high RPM operation, redesigned high-flow valves for adequate fuel delivery, and a fuel body casting that can be rotated to accommodate various plumbing situations. The inlet and outlet are tapped for 3/8" NPT, and it includes a fuel/vapor tube.
