We recommend also purchasing a Fuel Pressure Regulator to go with this carburetor. At this time, EMPI does NOT offer one, but you can easily source one from your local auto parts store. The EMPI Fuel Pressure Regulator #551-9102 has been discontinued by EMPI - they are working on finding another reliable way to reproduce these regulators. As soon as EMPI offers them again, we will have them available for purchase on our website.
