Z1's In-Tank Fuel Pressure Regulator Delete is used with fuel return systems to maintain the functionality of the venturi system in the fuel tank. This kit is included with the Z1 Fuel Return System and can also be used with custom fuel system solutions.
When installing an aftermarket fuel system and fuel pressure regulator, the factory regulator in the fuel pump basket is removed. Typically, when the factory regulator is removed the venturi system no longer functions. When Z1's Regulator Delete Kit is used, fuel is returned to the basket through the provided -6AN bulkhead fitting and through a specially machined fitting that feeds the original venturi system.
