Description

The #6 to 9/16-24 Holley/Demon Carb Adapter is an essential fitting for builders and mechanics upgrading or converting carburetor fuel delivery systems. This adapter bridges incompatible fuel line connections, allowing you to mate smaller #6 (3/8-inch) fuel lines to larger 9/16-24 threaded carburetor inlets found on Holley and Demon carburetors. Whether you're installing a modern fuel pump, custom fuel rails, or converting between carb models, this adapter eliminates costly rework and ensures a sealed, reliable connection that won't leak or fail under pressure.

Engineered with precision threading and durable materials, the #6 to 9/16-24 adapter features a stepped design that accommodates both inlet sizes without reducing fuel flow or creating turbulence. The 9/16-24 thread pitch is the industry standard for Holley carburetors and Demon performance models, ensuring a perfect fit with zero guesswork. Compact dimensions (2.7 x 1.25 x 4.05 inches) keep the adapter lightweight and unobtrusive in tight engine bays, while its compact 0.05-pound weight adds negligible burden to your fuel system. The adapter's straightforward design minimizes potential failure points and makes installation straightforward for both experienced fabricators and first-time builders.

This adapter is ideal for street rod builders, LS swap enthusiasts, and carb-to-EFI conversion projects where fuel line routing requires a size transition. It's equally valuable when upgrading from stock fuel systems to high-flow aftermarket carburetors or when plumbing custom fuel pressure regulators and filters. Technicians performing carburetor rebuilds and modifications will find this fitting indispensable for maintaining factory compatibility while accommodating non-original fuel supply lines. Use it with confidence on naturally aspirated and forced-induction engines; the adapter's robust construction handles fuel pressures typical of street and strip applications.
