When converting your fuel system to a return style EFI setup, the biggest challenge can be plumbing the fuel lines. The new Holley EFI Filter Regulator assembly simplifies your installation by combining the fuel filter and regulator in one assembly that can be mounted in the rear of the vehicle. Thus making your return line much shorter.
The die-cast aluminum assembly contains a 175 GPH 10 Micron filter and a regulator preset at 59.5 psi. This filter regulator features -8AN o-ring ports to match most EFI fuel systems.
Use the drop down menu to choose 8AN or 6AN (or no) adapters.
Features:
*10-micron filtration
*The fuel filter element is E85 friendly.
*Perfect for LS swaps, Coyote swaps, Gen 3 Hemi swaps, and other applications requiring 58-60psi.
*Not recommended for Gen 3 Coyote due to direct injection, an engine bay-mounted adjustable regulator is better suited for those.
