The Holley 34-21 Carburetor Fuel Inlet Fitting is a straight adapter designed to connect a 3/8 in. fuel hose directly to the 5/8-18 in. inverted flare inlet port on Holley 2010 and 2300 two-barrel carburetors. The straight configuration is ideal for applications where fuel line routing runs parallel to the carburetor inlet and clearance allows for a direct connection without bending.
