Fuel Cell Bulkhead Fitting -6AN to 3/8in

The Fuel Cell Bulkhead Fitting -6AN to 3/8in from Vibrant Performance is a critical component for custom fuel system builds, particularly in high-performance and motorsport applications where fuel cell tanks replace factory reservoirs. This bulkhead fitting serves as the sealed passage point through the tank wall, enabling clean fuel transfer from the cell to your engine's fuel rail while maintaining structural integrity and preventing leaks. Whether you're building a street machine, track car, or off-road rig with an aftermarket fuel cell, this fitting ensures a professional, leak-free connection at the tank interface.

Engineered with precision by Vibrant Performance, this bulkhead fitting features a -6AN outlet port that transitions to a 3/8-inch threaded connection for tank-side installation, accommodating both AN-style fuel lines and standard NPT adapters. The dual-port design allows fuel to enter or exit the cell while maintaining a sealed bulkhead interface—essential for preventing fuel vapor escape and protecting against contamination. Constructed from durable materials rated for modern fuel blends and high-pressure pump systems, this fitting handles the demands of both naturally aspirated and turbocharged fuel delivery setups without degradation or weeping.

Installation is straightforward for builders with basic fuel system knowledge—the 3/8-inch threaded base threads directly into the fuel cell's bulkhead hole, while the -6AN port accepts standard hose barbs, compression fittings, or swaged AN lines. This fitting is ideal for dual-fuel-pump setups, surge tanks, or any custom fuel cell configuration where you need a compact, reliable bulkhead pass-through. Verify your fuel cell's bulkhead hole diameter and threading before ordering, and pair this fitting with quality AN hose and properly sized fuel pumps for optimal system performance.
