2-1/4 Str. Filler Neck Dragster 6-Bolt Short

The 2-1/4 Str. Filler Neck Dragster 6-Bolt Short by JAZ is a purpose-built fuel system component engineered for high-performance dragsters and dedicated race vehicles. This filler neck assembly is designed for builders and mechanics who demand reliability and precision in fuel tank integration, particularly in applications where space is limited and weight matters. Whether you're constructing a bracket racer, Pro Stock competitor, or street strip dragster, this compact filler neck delivers the secure fuel inlet connection required for consistent performance at the strip.

The 2-1/4-inch straight neck design minimizes turbulence during fuel fill and maximizes flow efficiency, while the 6-bolt flange provides a bombproof mechanical connection to your fuel tank without relying on friction fittings that can loosen under vibration. The short configuration is critical for vehicles with tight engine bays or mid-engine layouts where traditional tall necks create clearance conflicts. JAZ's engineering prioritizes durability—the robust bolt-down design prevents fuel leaks and neck separation even under sustained g-forces and high-temperature engine conditions typical of drag racing. The compact 4.9 x 4.4 x 8.2-inch envelope and 1.15-pound weight mean you're not sacrificing valuable pounds where it counts.

This filler neck is ideal for racers building custom fuel cell systems, restomod dragsters, or any high-performance application requiring a compact, non-negotiable fuel inlet. Installation involves bolting the six-hole flange directly to your tank's prepared mounting surface—a straightforward job if your tank is already ported correctly. Verify your fuel tank has a 2-1/4-inch opening and a compatible six-bolt pattern before purchase. Pair this with quality fuel hose, a locking fuel cap, and a compliant fuel cell setup to complete a championship-grade refueling system that won't fail under race conditions.
