#8 Male to 5/16 Male Barb Bulkhead Fitting

The #8 Male to 5/16 Male Barb Bulkhead Fitting is an essential component for custom fuel system builds, turbo applications, and modified engine bay plumbing. Built by DEATSCHWERKS—a trusted name in high-performance fuel delivery systems—this fitting serves as a junction point for fuel lines, coolant loops, or boost-pressure lines in serious automotive modifications. Whether you're upgrading to a bigger fuel pump, installing a fuel surge tank, or routing boost tubes in a forced-induction setup, this barb bulkhead fitting provides a reliable, leak-free connection in tight spaces where standard straight fittings won't fit.

This fitting uses a barb-style connection on both ends, which grips hose securely without requiring crimped fittings or solder—critical when working with fuel-resistant braided hose or silicone lines in performance applications. The bulkhead design allows mounting directly through a panel or firewall, enabling clean routing and separation of pressurized circuits from engine heat and mechanical stress. The #8 SAE inlet (male) couples to 5/16-inch barb outlets, making it compatible with standard -6 AN hose sizing common in EFI fuel systems, turbo return lines, and coolant overflow plumbing. Compact dimensions (3.6 × 1.05 × 4 inches) ensure it fits tight engine bays without interfering with accessories or hose runs.

Serious tuners, engine builders, and LS-swap enthusiasts rely on DEATSCHWERKS fittings for fuel system integrity under boost and high-flow conditions. This barb bulkhead fitting is ideal for carbureted-to-EFI conversions, fuel cell installations, and dual-pump setups where flexible hose routing simplifies assembly and reduces risk of line fatigue. Install with appropriate hose clamps rated for your system pressure, and verify compatibility with your specific fuel type and operating temperature. At just 0.15 lbs, it adds negligible weight while delivering durability you can count on during weekend track days or daily driving in modified vehicles.
