Fuel Pump, Mechanical, Holley, Big Block Chevy, 3/8" NPT Inlet/Outlet

Chevrolet Big Block Mechanical Fuel Pump, 110 or 130 GPH by Holley®

The rotatable polished aluminum housing positions the 3/8" NPT ports for fuel-line routing.

This Holley® mechanical fuel pump supplies carbureted Chevrolet Big Block engines and uses a polished aluminum housing that can rotate through 360 degrees to position the inlet and outlet for fuel-line routing. Both ports are 3/8" NPT. The 110-GPH version is rated at free flow, with a preset shutoff pressure of 6.5-8 psi and no separate regulator required. The 130-GPH option has a 130-plus-GPH free-flow rating, 7.5-9 psi preset shutoff pressure and high-flow valves; it requires a fuel pressure regulator. Both versions are intended for sustained high-rpm street/strip use with gasoline. A gasket or seal is included; mounting hardware is not.
