Holley In-Tank Carbureted Retrofit Fuel Pump Module

• Holley In-Tank Retrofit Fuel Pump Module offers a quiet, in-tank fuel delivery option for carbureted vehicles, eliminating the need for cutting, welding, or custom fabrication
• Compact 5-inch diameter, low-profile assembly equipped with a 255 LPH pump and integrated regulator tailored for carburetor applications
• Capable of supporting up to 700 horsepower in carbureted setups at 6 PSI and 13.5 volts, with an approximate 10.4 amp draw depending on overall system configuration
• Designed to fit fuel tanks ranging from 6.5 to 12 inches in depth for versatile installation
• Constructed from die-cast aluminum and features a pump hanger bracket to help minimize vibration and resist corrosion
• Utilizes a unique clamping mechanism with full 360-degree rotation, 1/4 inch NPT ports, and the ability to upgrade the regulator for future EFI conversion
• Covered by a 1-Year Limited Warranty

Traditional external electric fuel pumps have long been common on street and strip vehicles, but in-tank designs offer advantages such as reduced noise and improved fuel control. If you are updating a carbureted combination and want the benefits of an in-tank system without extensive modifications, the Holley In-Tank Carbureted Retrofit Fuel Pump Module provides a practical solution.

This module features a compact 5-inch diameter layout similar to many EFI-style assemblies and is equipped with a 255 LPH fuel pump and an integrated regulator configured for carbureted applications. It is capable of supporting up to 700 carbureted horsepower at 6 PSI and 13.5 volts, drawing approximately 10.4 amps, though actual performance depends on the overall fuel system design. The unit is designed to fit fuel tanks ranging from 6.5 to 12 inches in depth and installs without the need for welding or fabrication.

Constructed from die-cast aluminum for corrosion resistance, the module includes a pump hanger bracket to help minimize vibration while maintaining a low 1.275-inch profile above the tank mounting surface for improved clearance. Its clamping mechanism allows installation in a wide range of tank locations with full 360-degree rotation to simplify fuel line routing and wiring orientation. The assembly uses 1/4-inch NPT ports for flexible plumbing options, and the internal regulator can be replaced if converting to EFI in the future. Backed by a 1-Year Limited Warranty.
