Holley Retrofit 255-LPH Fuel Pump Module with a Fuel Return Line.
For applications with a fuel tank that’s 7” to 12” deep, this Holley fuel pump module is a great way to customize your build (12-136). Provided that you’re using gasoline, this 255-LPH module can support up to 700 carbureted horsepower at 60 PSI and 13.2 volts. Alternatively, it can handle 550 EFI running at the same PSI and volt levels. Not only does this make it great for powerful setups, but it’s also excellent for clearance. This is thanks to the low-profile design, which sits at a 5” diameter and a 1.275” thickness above the tank mounting surface.
