When converting your fuel system to a return-style EFI setup, the biggest challenge can be plumbing the fuel lines. Holley has found a way to make this job easier! The new Holley EFI filter regulator assemblies simplify your installation by combining the fuel filter and regulator in one assembly that can be mounted in the rear of the vehicle. Being mounted in the rear means less line to run for a return and less mess. These regulators feature a 175 gph, 10 micron fuel filter. The regulators are preset at 59.5 psi. These Holley EFI filter regulators are available in 3/8 NPT or -8 AN port sizes to match most common EFI fuel systems. Simplify your EFI conversion, or clean up the plumbing on your current EFI system, by using one of these Holley EFI filter regulators today.
