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!
