3-12 psi Adjustable Universal Deadhead Fuel Pressure Billet Regulator Blue so it is not necessaryThe 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.
