The Aeromotive EFI to Carburetor Dual Stage Fuel Pressure Regulator (Part Number 13220) is designed to simplify the process of converting a return-style EFI fuel system to a carbureted setup without extensive modifications. This innovative regulator allows any car or truck originally equipped with EFI to seamlessly switch to a carburetor while maintaining compatibility with the original fuel system components, including the stock pump, supply and return lines, and fuel filter. Installation is straightforward thanks to universal 3/8 inch NPT ports for inlet, outlet, and return, enabling easy plumbing with standard fittings. The regulator's dual stage design provides precise pressure control, with the first stage adjustable from 8 to 16 psi to bypass excess fuel pressure and protect the EFI pump, and the second stage adjustable from 5 to 9 psi to supply the carburetor with optimal fuel pressure. This setup ensures stable fuel delivery, aiding in engine performance and reliability. Two 1/8 inch NPT gauge ports facilitate pressure monitoring and adjustment for both stages, allowing for fine-tuning to suit specific engine requirements. The Aeromotive EFI-2-Carb regulator enhances vehicle versatility and can help restore or upgrade older vehicles to run efficiently with a carburetor, eliminating the need for costly fuel system overhauls or complex diagnostics. Compatible with standard fittings such as 3/8 inch NPT to AN or barb fittings, it offers flexible installation options. Built with quality components, this regulator provides a reliable solution for enthusiasts seeking to convert EFI systems to carbureted setups without sacrificing fuel system integrity or performance.
