This in-tank fuel pump module flows 255 liters per hour and supports EFI engines producing up to 550 horsepower on 1968-1972 GM A-Body applications. It installs as a direct replacement for the factory pick-up and sending unit, so the factory fuel hard line can be retained, and fuel pressure is internally regulated to 58 psi, eliminating the need for a separate external regulator or return line. A Holley HydraMat internal reservoir helps prevent fuel starvation during hard cornering, acceleration, braking, and low-fuel conditions.
