Carb Base Gasket, for Weber IDA & EPC 51 Carbs, Pair

EMPI Carburetor Base Gaskets for Weber 51 IDA and EPC Carbs

Product Overview and Compatibility

This pair of EMPI carburetor base gaskets is designed specifically for high-performance Weber 51 IDA and EPC 51 series carburetors. These gaskets provide a critical seal between the carburetor base and the intake manifold, ensuring that your engine maintains proper vacuum pressure for optimal performance. Sold as a pair, these are essential components for any dual-carburetor rebuild or installation on performance VW engines. Part Number: 00-3398-0.

Air-Cooled VW Fitment Information

These gaskets are primarily used in high-performance Air-Cooled VW applications including the Type 1 Beetle, Karmann Ghia, Type 2 Bus, and Dune Buggies equipped with aftermarket 51mm IDA or EPC dual-carburetor kits. Because these carburetors are significantly larger than stock units, these specific gaskets are required to match the larger bore size of the 51mm series and ensure no restriction of airflow.

Pro Tech Tips for Installation

Tip 1: Surface Preparation. Always ensure that both the intake manifold flange and the carburetor base are perfectly clean and flat. Use a gasket scraper or fine abrasive to remove all traces of old gasket material, as even a small piece of debris can cause a significant vacuum leak that affects idle quality.

Tip 2: Avoid Liquid Sealants. Do not use RTV or silicone sealants on these gaskets. These materials can squeeze out into the intake path or clog internal carburetor passages. These gaskets are manufactured to seal effectively when installed dry or with a very light coating of specialized gasket tack if necessary.

Tip 3: Proper Torque Sequence. When installing the carburetor onto the manifold studs, tighten the mounting nuts gradually and in an alternating pattern. Over-tightening one side first can warp the carburetor base or the manifold flange, leading to permanent damage and persistent air leaks that are difficult to diagnose.
