8-21/32in Fuel Line W/Gauge

The 8-21/32in Fuel Line with Gauge from Mr. Gasket is a purpose-built fuel delivery system designed for carburetor-equipped performance vehicles, particularly those running Holley 4160 carburetors. This dual-outlet configuration serves both fuel pressure monitoring and reliable supply delivery—critical for tuners and mechanics working with classic hot rods, street machines, and vintage muscle cars where accurate fuel system diagnostics are non-negotiable. The integrated fuel pressure gauge allows real-time observation of system pressure, eliminating guesswork during tuning and troubleshooting.

This fuel line assembly features a 5/8-18 inch inverted flare female inlet connection mated to dual 5/8-18 inch inverted flare male outlets, providing redundant fuel delivery paths while maintaining pressure uniformity across the system. The all-steel, chrome-finished construction delivers durability and corrosion resistance essential for underhood environments, while the inverted flare fittings ensure leak-free sealing under load. The integrated gauge mount positions the pressure indicator within easy visual range, enabling carburetor tuning without external adapters or gauge blocks that compromise appearance or create potential leak points.

Mechanics and performance enthusiasts working with Holley 4160 carburetors will find this assembly indispensable for baseline fuel system validation and ongoing maintenance diagnostics. The dual outlet design accommodates overflow return lines or secondary fuel circuits common in carbureted racing and street applications. Installation requires basic fuel line knowledge and hand tools compatible with 5/8-inch flare connections; proper torque and sealing compound application ensures years of trouble-free operation. Weighing 0.93 lbs and measuring 8-21/32 inches overall, this fuel line integrates seamlessly into both tight engine bays and custom fuel system layouts.
