Chrome Fuel Line 8-21/32

The Chrome Fuel Line 8-21/32 from TRANS-DAPT is a precision-engineered fuel delivery component designed for serious carburetor builds and high-performance engine swaps. Built specifically for carburetors like the Holley 4160, this chrome fuel line bridges the gap between modern fuel systems and classic carburetor inlets with professional-grade reliability. Whether you're restoring a vintage engine, upgrading to a carbureted platform, or fine-tuning fuel delivery on a street machine, this fuel line eliminates guesswork and delivers consistent flow from tank to carb.

Manufactured from steel with a durable chrome finish, the Chrome Fuel Line 8-21/32 features a 3/8-inch single hose barb inlet connection for secure attachment to your fuel supply line, paired with dual 5/8-18-inch inverted flare male outlets that thread directly into Holley carburetors and similar applications. The included 1/8-inch NPT gauge port allows you to install a fuel pressure gauge for real-time monitoring—critical for tuning and diagnostics on any carbureted engine. The inverted flare design ensures positive, leak-free seals under pressure without requiring extra adapter fittings, reducing complexity and potential failure points in your fuel system.

This fuel line is ideal for mechanics and enthusiasts performing engine conversions, carb swaps, or fuel system upgrades on hot rods, classic trucks, and performance street engines. The compact 8-21/32-inch length fits tight engine bay configurations while the chrome plating adds a finishing touch visible through an open hood. Installation is straightforward—simply connect your fuel supply hose to the barb inlet and thread the flare outlets into your carburetor's fuel ports, then attach your gauge if desired. Ensure your fuel pump pressure is set within carburetor specifications (typically 4–7 psi for most float-bowl carbs) to maximize performance and prevent lean-out conditions.
