• The easiest way to convert your vehicle to an in-tank, EFI fuel system
• Installs in any fuel tank from 8.5” to 12” deep to fit a wide variety of applications
• The low profile design is only 1.275″ thick 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” x 15” HydraMat mounting flange has 6 clocking pin locations to allow for 360 degree adjustment to clear sending unit levels or any tank floor restrictions that you might encoun
• Black anodized aluminum construction for corrosion resistance and long lasting good looks
• ¼” NPT ports for a wide variety of plumbing options
• Ideal for Terminator EFI, Sniper EFI, MSD Atomic EFI or any TBI of EFI conversion
• Optional roll over valve available
• Two different fuel pumps are available to match your requirements – 255LPH or 400LPH for both return and returnless style systems
• Eliminates the need for a return line and conventional fuel pressure regulator. Thus, simplifying your installation
• Includes an internal fuel pressure regulator preset at 60 psi for a wide variety of applications. No return line required!

*Installation Note: It is recommended to use a Holley 12-753 30 Amp Fuel Pump Relay along with a minimum size of 12 Gauge wire for your installation. Maximum 6AN line and fitting size due to space limitations between unit and fuel tank.

Installation Instructions

Supports up to 875 EFI or 1100 Carb HP (@ 60 PSI at 13.5 Volts / 16.9 AMP Draw) Of course there are many variables, estimates are based on gasoline. Individual systems will vary based on fuel system design, regulator type, fuel cell location, etc…
