This in-tank fuel pump module is a direct replacement for the factory pick-up and sending unit in 1970-1974 Dodge Challenger and Plymouth Barracuda fuel tanks, eliminating the need for a custom EFI tank. The factory fuel hard line can be retained by connecting the module outlet to it with EFI-rated hose and clamps. A 255 LPH pump and a Holley HydraMat fuel reservoir system are built in to reduce fuel starvation during cornering, acceleration, braking, and low-fuel conditions.
