Holley & Carter Carb 1in 3/4 Dia 4 Hole Gasket

The FEL-PRO Holley & Carter Carb 1 inch 3/4 Diameter 4 Hole Gasket (MPN 1901) is a composite carburetor base plate gasket engineered for square bore four-barrel carburetor applications. This 0.063-inch thick gasket delivers reliable sealing at the critical interface between the carburetor body and intake manifold, where fuel-air mixture delivery depends on consistent gasket integrity.

FEL-PRO's composite construction provides superior compression recovery compared to cork or single-material gaskets, maintaining sealing force across thermal cycles and engine vibration. The four-hole design accommodates standard square bore carburetor mounting patterns, while the 1-inch 3/4 inch diameter specification ensures proper coverage of the base plate sealing surface. This gasket handles both street and performance applications where fuel metering accuracy and intake manifold vacuum integrity are essential.

Mechanics and engine builders working on classic muscle cars, hot rods, and vintage truck platforms rely on proper base plate gasket selection to prevent fuel seepage, air leaks, and erratic idle conditions. OEM replacement or performance rebuild work demands a gasket that resists fuel chemical attack, maintains gasket crush under clamp load, and survives repeated carburetor removal and reinstallation cycles. This single gasket is supplied individually, so verify quantity requirements before checkout.

FEL-PRO gaskets are manufactured to OEM specification standards and are widely stocked by professional shops and serious enthusiasts. Proper installation includes checking the carburetor base plate and intake manifold mounting surface for flatness and cleanliness before assembly to maximize gasket lifespan and sealing performance.
