This is a primary fuel bowl for the Holley 4180 carburetor. This carburetor was used on many OE Ford trucks that came from the factory with a Holley 4bbl carburetor. This is a discontinued item from Holley. Pictured is the Replacement fuel bowl, that we offer. It is complete and comes with the necessary gasket to put back on the carburetor. A picture of the original fuel bowl is here for comparison only, so that you can compare it to the new bowl. Notice that the replacement bowl does NOT have the vent pipe, and will require a rubber fuel supply hose to connect to the pipe on the new fuel bowl.
