3-12 psi Adjustable Universal Deadhead Fuel Pressure Billet Regulator Blue These Speedmaster supercharger manifolds areThe needle and seat assemblies that are installed in Speedmaster carburetors can sufficiently control fuel pressure up to about 8 psi. If the fuel pump is putting out more than 8 psi, a regulator should be used to keep the fuel pressure within safe limits and avoid the possibility of flooding. Speedmaster manufactures a number of regulators for most any need.
