2-1/2 Str. Filler Neck Dragster 6-Bolt Long

The 2-1/2 Str. Filler Neck Dragster 6-Bolt Long by JAZ is purpose-built for serious drag racing and high-performance fuel system upgrades where reliability and durability meet extreme competition demands. This filler neck assembly serves as the critical fuel intake point on custom-built dragsters and fuel-injected race cars, where OEM components simply cannot withstand the rigors of bracket racing, bracket drag racing, or circle track competition. Whether you're running a dedicated drag platform or converting a street machine into a weekend warrior, this JAZ component ensures fuel system integrity under sustained high-RPM conditions and rapid fuel consumption cycles.

Built with a 2-1/2-inch straight configuration and secured via a robust 6-bolt flange design, this long filler neck provides superior fuel cell integration and clearance for complex engine bay layouts common in tube-frame dragsters and modified street machines. The straight geometry minimizes fuel sloshing during hard acceleration and braking events, reducing the risk of fuel starvation during critical moments in the race. JAZ engineered this assembly with materials and construction methods rated for consistent performance in fuel systems pressurized by high-volume fuel pumps, making it compatible with both carbureted and EFI setups that demand precision and longevity in extreme-duty applications.

Ideal for fabricators, professional drag racing teams, and dedicated enthusiasts building or upgrading fuel cells in dragsters, the 2-1/2 Str. Filler Neck Dragster 6-Bolt Long integrates seamlessly with aftermarket fuel cell configurations and racing-spec fuel systems. Its 6-bolt long pattern ensures secure mounting to standard fuel cell bungs and custom tank designs, while the 2-1/2-inch diameter accommodates high-flow fuel nozzle pumps without restriction. Installation requires basic mechanical skill and standard hand tools; proper alignment and torque specifications should follow JAZ guidelines to guarantee system integrity across multiple competition seasons.
