Holley Diecast In-Tank Retrofit Fuel Pump Modules

Holley diecast in-tank retrofit fuel pump modules are quick and easy ways to convert your factory tank or fuel cell into an EFI in-tank fuel system, while also adding the benefits of a Holley HydraMat in the process! The conversion is easily accomplished with basic tools and requires no welding or fabrication. The aluminum module design includes a diecast pump hanger bracket to control pump vibration, while also providing a low-profile design to fit where space is at a premium. Holley's innovative clamping system and integrated fuel pump makes it a simple install. Interested in an EFI retrofit kit, but can't get past the complicated fuel system? Holley diecast in-tank retrofit fuel pump modules are your solution. They're available in various flow rates, as well as return and returnless versions.

Features include:

* Installs in any fuel tank from 6.5 in. to 12 in. deep (depending on kit) to fit a wide variety of applications
* The low-profile design is only 1.275 in. above the tank mounting surface for added clearance when needed
* The innovative clamping system allows you to locate the module anywhere in the tank beside your existing sending unit
* The clamping system allows you to rotate the unit 360 degrees for easier clocking of the plumbing and wiring locations under your ride
* Includes innovative Holley HydraMat to ensure consistent fuel supply. The 3 in. x 15 in. HydraMat mounting flange has six clocking pin locations to allow for 360 degrees of adjustment to clear sending unit levels or any tank floor restrictions that you might encounter
* Diecast aluminum construction for corrosion resistance and long-lasting good looks
* 1/4 in. NPT ports for a wide variety of plumbing options
* Ideal for Terminator EFI, Sniper EFI, MSD Atomic EFI, or any TBI or EFI conversion
* Two different fuel pumps are available—255 lph or 400 lph for both return and returnless-style systems
