The Aeromotive EFI‑to‑Carb dual‑stage fuel pressure regulator allows return‑style EFI systems to run a carburetor without reworking the stock fuel system. The two stages let you adjust pump bypass pressure (8–16 psi) and carb feed pressure (5–9 psi) independently, with universal 3/8" NPT inlet, outlet and return ports and two 1/8" NPT gauge ports for monitoring. It supports simple plumbing using standard fittings.
