#12 Fuel Cell Bulkhead Fitting Black

The #12 Fuel Cell Bulkhead Fitting Black by FRAGOLA is a straight-through adapter designed for high-flow fuel system installations where two fuel lines must pass through a bulkhead wall or panel. Built for serious fuel cell builds, race car fuel systems, and custom automotive projects, this fitting eliminates the need for external fittings that would otherwise protrude into engine bays or cabin spaces. Whether you're constructing a fuel cell mounting system, plumbing a custom fuel tank, or upgrading an existing fuel delivery network, this bulkhead fitting provides a clean, secure pass-through solution that professional fabricators and performance enthusiasts rely on.

This fitting features a 12 AN male-to-male bulkhead design, meaning both inlet and outlet ports accept standard -12 AN hose ends or hard-line adapters. The aluminum construction with black anodized finish resists corrosion while maintaining a professional appearance in exposed fuel cell installations. The straight configuration allows unobstructed flow without bends, critical for fuel delivery systems where pressure drop and turbulence must be minimized. The bulkhead design incorporates a threaded body that locks firmly into a drilled panel, with the flange on the backside preventing pull-through and ensuring a permanent, leak-free seal when properly installed with appropriate sealing tape or thread-locking compound.

This #12 Fuel Cell Bulkhead Fitting is ideal for fabricators building fuel cells, custom race vehicles, or vehicles with relocated fuel tanks. It pairs seamlessly with 12 AN braided hose, hard-line tubing, and standard fuel system components in the FRAGOLA ecosystem. Installation requires drilling a clean hole through your fuel cell, tank wall, or bulkhead, then threading the fitting from inside and sealing from both sides. The compact dimensions and light weight make it an efficient choice where space constraints exist. Mechanics and fabricators trust FRAGOLA fittings for their durability, precise machining, and resistance to fuel degradation—essential qualities in high-performance and endurance racing applications.
