10an Bulkhead Fitting

The AEROMOTIVE 10AN Bulkhead Fitting (Part No. 15686) is an essential component for any serious fuel system build, whether you're upgrading a carbureted engine, installing an EFI conversion, or designing a custom fuel cell setup. Bulkhead fittings serve as the sealed pass-through connection that allows fuel lines to exit a tank or reservoir without leaking, making them indispensable in racing, off-road, and high-performance street applications.

This straight configuration offers straightforward installation and eliminates complex angle adapters, reducing failure points and simplifying plumbing logistics. Engineered to AN 10 standard specifications, this fitting is compatible with -10 braided hose or hard-line fuel lines using industry-standard AN compression connections. The bulkhead design features an internal seal and external mounting surface, allowing you to drill a single hole through your fuel tank wall or reservoir and secure the fitting from both sides.

Fabricators, engine builders, and vintage car restorers benefit most from this fitting when designing custom fuel system layouts or transitioning between tank designs without modifying existing AN setups. Its robust design withstands vibration and thermal cycling, ensuring a reliable and leak-proof junction for various fuel system applications.
