Differential Ring and Pinion

The easiest way to convert your vehicle to an in-tank, EFI fuel system. Installs in any fuel tank from 7" to 12" deep to fit a wide variety of applications. The low profile 5 inch diameter design is only 1.275 inches 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. Black anodized aluminum construction for corrosion resistance and long lasting good looks. 1/4" 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.
