Aeroquip Carburetor Adapter Plate
Aeroquip Carburetor Adapter Plates: Precision Fuel System Connections
When it comes to connecting a performance carburetor cleanly and reliably to your fuel system, few names carry as much credibility as Aeroquip. Founded in 1940, Aeroquip built its reputation first in military aviation before becoming a cornerstone of motorsport plumbing — and that pedigree shows in every carburetor adapter plate and fuel system fitting the brand produces.
Carburetor adapter plates serve a critical role in any carbureted fuel delivery build: they bridge the gap between incompatible bolt patterns, carburetor inlet threads, and AN-style performance hose ends, allowing builders to run clean, leak-free plumbing instead of relying on bulky stock hardware. Getting this connection right matters for both performance and safety, and it is exactly where Aeroquip has distinguished itself for decades.
What Makes Aeroquip Stand Out in Carburetor Adapters
Aeroquip's carburetor adapter fittings are machined from high-quality aluminum and finished with their recognizable blue or black anodized coating, or a nickel-plated finish — finishes that protect against corrosion and give any engine bay a clean, professional look. The adapters are designed to provide an easy AN hose-end connection to carburetor inlets, making it straightforward to plumb a braided fuel line directly to Holley single, dual, Quadrajet, or Dominator series carburetors. The lineup includes AN-to-inverted-flare straight adapters, carburetor inlet fittings in -6 AN male configurations, and fittings in a range of thread pitches (7/8-20, 9/16-24, 5/8-20) to match the inlet port on virtually any popular carburetor.
Aeroquip engineers these adapters to exceed industry tolerances, delivering improved uninterrupted fuel flow and worry-free reliability under sustained high-performance use. As a brand that has been the choice of motorsport professionals and enthusiasts for over 80 years, Aeroquip understands that a fuel system fitting is not just a convenience part — it is a safety-critical component that must seal perfectly every time.
Compatibility and Application
The Aeroquip carburetor adapter lineup is designed primarily as universal, non-application-specific hardware, making it ideal for custom builds, engine swaps, and race car fabrication where stock fuel routing simply won't do. Builders appreciate the versatility of choosing between AN-to-inverted-flare adapters for integrating into braided stainless or AQP hose systems, and the availability of both bulk-packaged (FB-prefix) and retail-carded (FC-prefix) versions, so whether you are stocking a shop or completing a single build, there is an option to suit.
