Earl's Performance Fuel Cell Bulkhead Fittings

Earl's Performance Fuel Cell Bulkhead Fittings are purpose-engineered for high-performance fuel system fabrication where a reliable, leak-free connection through the cell wall is critical. Featuring a radius-tapered inlet design, these high-flow fittings maximize fuel delivery by promoting smooth, unrestricted flow and minimizing turbulence at the bulkhead interface — making them an ideal choice for fabricated tanks, plastic or metal fuel cells, and a wide variety of custom plumbing applications.

Key Features:

• Radius-tapered inlet promotes high-volume, smooth fuel flow and reduces pressure drop at the cell wall
• High-flow construction engineered to support maximum fuel delivery demands in performance and racing applications
• Purpose-built bulkhead geometry creates a proper, pressure-tight seal through fuel cell walls
• Durable aluminum construction with a corrosion-resistant black anodized finish for long service life in demanding environments
• Complete hardware included — each fitting ships with two PTFE washers and a bulkhead nut for a professional, ready-to-install solution
• Versatile application — suitable for fabricated tanks, plastic and metal fuel cells, valve cover breathers, fabricated tank drains, and custom plumbing configurations
• Available in multiple AN sizes to accommodate a wide range of fuel system layouts and flow requirements

Earl's Performance Products has been at the forefront of motorsport plumbing since 1955, when founder Earl Fouts began supplying the racing industry with high-quality fluid transfer components. Earl's pioneered the self-indexing Swivel Seal hose end and introduced flexible armored PTFE-lined hose to motorsports — innovations that define performance plumbing to this day. Top funny car, sprint car, and Indy car teams continue to rely on Earl's products, and Earl's plumbing has been aboard the vast majority of Indianapolis 500 winners. These fuel cell bulkhead fittings carry on that legacy of precision engineering, delivering the flow capacity and sealing integrity that professional fuel system builders and motorsports fabricators demand.
