Aeromotive EFI-2-Carb Dual Stage Fuel Pressure Regulator (3/8in NPT) - 13220

The Aeromotive EFI-2-Carb Dual Stage Fuel Pressure Regulator (P/N 13220) provides a streamlined solution for converting any car or truck with a return-style EFI system to a carburetor. This innovative component allows you to retain your factory EFI fuel pump, supply and return lines, and fuel filter while delivering the precise, low-pressure flow required for a carbureted setup.

By utilizing a dual-stage regulation process, this unit maintains the necessary bypass pressure to keep high-pressure EFI pumps operating within their design parameters while independently controlling output to the carburetor. This prevents pump cavitation and overheating while ensuring the carburetor floats receive the exact pressure needed. The 3/8-inch NPT ports allow for easy plumbing with standard fittings or AN adapters.
