IAP 113129731 Carburetor Fuel Inlet Needle & Seat Assembly for Air-Cooled VW

The IAP 113129731 is a carburetor fuel inlet needle and seat assembly sourced from IAP (International Auto Parts), a trusted supplier specializing in components for classic air-cooled Volkswagen vehicles. This precision replacement part is designed to restore proper fuel metering and float bowl fuel level control in OEM-style carburetors commonly found on vintage VW applications.

The needle and seat assembly plays a critical role in the carburetor's fuel delivery system — regulating the flow of fuel into the float bowl to maintain the correct fuel level for consistent air/fuel mixture and reliable engine performance. A worn or leaking needle and seat is one of the most common causes of carburetor flooding, fuel overflow, and poor idle quality.
