The needle and seat assemblies that are installed in Holley Performance 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. Holley manufactures a number of regulators for most any need.

Second purchase of this regulator.

Summit RacingSummit Racing Verified Purchase

My first purchase of this regulator was a package deal with a new fuel pump, but lost both in an electrical fire. So when it came time to rebuild I came back to the same one. Hard to beat the price and quality.
