Aeromotive?s New EFI-2-Carb Dual Stage Fuel Pressure Regulator P/N 13220 allows any car or truck, originally equipped with a return-style EFI powered engine, to affordably convert to a standard carburetor, all while retaining the full, stock, EFI fuel system components? All with a single regulator. With the New EFI-2-Carb Dual Stage regulator, no changes to the original EFI fuel system are required to bolt on a carburetor and go.? Allows use of the stock EFI pump in the tank, the stock EFI supply and return lines, and the stock fuel filter.? This amazing new dual stage pressure regulator provides seamless control of bypass pressure to keep the EFI fuel pump happy while enabling full control of output pressure low enough to feed any off-the-shelf carb. In the first stage, pump bypass pressure is adjustable from 8-16 psi.? In the second stage, pressure to the carburetor is regulated and adjustable from 5-9 psi.? Installation is painless thanks to universal, 3/8? NPT inlet, outlet and return ports.? Two 1/8? NPT gauge ports allow both first stage line pressure and second stage carbureted pressure to be adjusted and monitored.? Ordinary 3/8? NPT to AN, or 3/8? NPT to barb fittings may be used, making plumbing easy to do and the fittings inexpensive. The new EFI-2-Carb Dual Stage regulator from Aeromotive allows you to get an otherwise good car or truck running and back on the road again, easily and affordably.? No need to spend an arm and a leg, or countless hours, diagnosing and/or repairing a complicated, worn out EFI system.? And, no more need to perform a costly redo of the fuel system just to install a carburetor.
Aeromotive
Aeromotive has been the standard for high-performance fuel delivery since 1994, engineering fuel pumps, regulators, filters, and complete fuel system kits trusted by professional racers and serious street car builders. If your engine is making big power — whether on forced induction, nitrous, or a naturally aspirated high-displacement build — Aeromotive's catalog has the components to keep fuel supply ahead of demand under every condition.Popular UpgradesThe Aeromotive Stealth 340 and Phantom in-tank fuel pump systems are top sellers for builds that demand consistent flow without external pump mounting. The A1000 external fuel pump remains a proven choice for high-horsepower carbureted and EFI applications. Billet fuel pressure regulators from Aeromotive allow precise adjustability for return-style systems, and complete stealth fuel system kits offer a clean, all-in-one solution for builders who want maximum reliability from a single supplier.What flow rate do I need for my power le...

Fuel Delivery
A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

Fuel Pressure Regulators
A fuel pressure regulator maintains consistent rail or bowl pressure regardless of engine demand, fuel pump output variation, or manifold vacuum changes, acting as the pressure control valve that determines how much fuel the injectors or carburetor actually sees at any given moment. In return-style EFI systems, the regulator bleeds excess fuel back to the tank while holding the supply side at a precise setpoint, typically 43.5 PSI for most port EFI applications. In boost-referenced setups, the regulator increases fuel pressure proportionally with boost pressure to maintain a constant fuel-to-air pressure differential as manifold pressure rises, preventing the injector effective flow rate from dropping under boost. Selecting the correct regulator type, pressure range, and port sizing for your system determines how accurately fuel delivery tracks engine demand across the full operating envelope.
