#10 Female to #8

The EARLS #10 Female to #8 Male Straight Adapter Fitting is a precision hydraulic and fuel system connector engineered to bridge two different AN port sizes in a single, compact assembly. This aluminum adapter accepts a #10 AN female port and connects to a #8 AN male fitting, making it essential for custom fuel system layouts, pressure line installations, and high-performance engine bay configurations where port size transitions are required.

Constructed from aluminum and finished in blue anodize, this straight-configuration adapter delivers reliable leak-free connections in both street and racing applications. The anodized coating provides corrosion resistance critical for fuel system integrity, while the aluminum construction keeps weight minimal—a key consideration in performance and custom builds. The #10-to-#8 sizing transition is a common requirement when integrating aftermarket fuel filters, regulators, or custom fuel rails into existing or modified engine bay layouts. EARLS adapters meet strict industry flow and pressure specifications, ensuring compatibility with fuel injection systems and carburetor feed lines alike.

This fitting is designed for builders and technicians who demand precision in custom fuel system assembly. Whether you're installing a new fuel system in a restoration project, adapting legacy plumbing to modern fuel components, or fabricating a high-flow racing fuel setup, port size mismatches are solved reliably with a single connector. The straight design minimizes flow turbulence and pressure drop compared to elbows, making it ideal for main fuel distribution lines where smooth flow and quick assembly matter.

AN (Army-Navy) adapters are the industry standard for high-performance fuel and hydraulic systems because they deliver predictable, repeatable connections without the port deformation risks of compression fittings. EARLS has built its reputation by holding tight tolerances on all adapter configurations, and this #10-to-#8 straight adapter reflects that commitment to precision and long-term reliability in demanding engine applications.
