Aeromotive Adjustable Carbureted Regulator from 5-12 lbs

715-13201

Adjustable Carbureted Regulator from 5-12 lbs

Aeromotive carbureted fuel pressure regulators are true billet regulators. A convoluted diaphragm maximizes piston stroke and increases flow - without stressing the diaphragm. Every Aeromotive carbureted regulator incorporates a poppet design unique to that regulator, and we fabricate the diaphragms from our proprietary elastomer material Precision engineering and manufacturing translate into tight fuel pressure control.

Note: Uses -6 O-ring style fittings

Aeromotive Carburetor Equipped Boost Reference Fuel Regulator

715-13204

Carburetor Equipped Boost Reference Fuel Regulator

For those of you unfamiliar with boost referencing of a fuel system, well it's the ultimate way to meet fuel supply demands on a supercharged engine. By connecting a hose from your intake manifold to the top fitting of this regulator you can control fuel pressure on demand. You see for every pound of boost your engine generates it will allow the regulator to increase fuel pressure by the pound. These features have been used by professional race teams for years.

  • Base fuel pressure adjustable from 3-15 PSI. 
  • (1) ORB-10 inlet port and (1) ORB-08 return port.
  • P/N 13204 provides (2) ORB-06 outlet ports and 1/8' NPT gauge port.
  • Fuel pressure rises on a 1:1 ratio when referencing boost.
  • Bypass design provides the ultimate, dynamic fuel delivery system.
  • Ideal for converting from fuel injection to carburetion using the stock, in-tank pump.
  • EFI conversions will require a larger-than-stock return line for proper low pressure control.
