The Holley "red and blue" electric fuel pumps have set the standard for performance for many years. While they still deliver reliable performance, advancements in fuel pump technology have introduced quieter operations and improved fuel delivery capabilities that in-tank modules can provide.

Looking towards the future, Holley has crafted their latest retrofit pump module specifically for carbureted applications. This module mirrors the design of existing EFI pump modules, featuring a robust 255 LPH pump, but comes equipped with a built-in regulator tailored to the lower fuel pressure that carburetors need.

Now, you can easily convert your factory tank or fuel cell to an in-tank fuel system without the hassle! This conversion can be done with just basic tools, and there's no need for welding or fabrication. The aluminum module design is paired with a die-cast pump hanger bracket to minimize pump vibration while maintaining a low profile for tight spaces. With Holley’s ingenious clamping system and integrated fuel pump, installation is a breeze. Once everything is set up, just connect your fuel lines and power source, and you're ready to hit the road!

As a bonus, if you decide to upgrade to an EFI system down the line, you can easily swap out the internal regulator in this module.

This setup supports up to 700 Carb HP at 6 PSI with 13.5 Volts and a 10.4 AMP draw. Keep in mind that various factors can influence performance, and these estimates are based on gasoline. Your individual system may vary depending on design and fuel cell location.
