Carb Adj. Fuel Line

The MR. GASKET Carb Adj. Fuel Line is a precision-engineered carburetor fuel delivery component designed for high-performance and street engine builds requiring flexible, adjustable fuel routing. Built for enthusiasts and professional mechanics upgrading or rebuilding Holley 4150 and 4160 carburetors, this adjustable fuel line eliminates rigid hard-line plumbing constraints while maintaining reliable fuel flow under varying engine conditions. Whether you're fine-tuning fuel delivery on a modified engine or transitioning from mechanical to carb-based fuel systems, this component provides the control and durability needed for consistent carburetor operation.

Constructed from braided stainless steel with a 3/8-inch hose barb inlet, the Carb Adj. Fuel Line features dual 5/8-18 inverted flare male outlets that connect directly to Holley four-barrel carb inlets with industry-standard flare fittings. The adjustable design allows technicians to angle and position the fuel line for optimal engine bay packaging and fuel filter integration, reducing clearance issues common in tight installations. Chrome, blue, and red finish options provide both corrosion resistance and aesthetic appeal, while the braided construction withstands pressure fluctuations and vibration inherent in street and race applications without kinking or collapsing.

Ideal for carburetor rebuilds, engine swaps, and fuel system upgrades on classic and modern muscle cars, hot rods, and street machines, this adjustable fuel line simplifies installation where hard fuel lines prove impractical. Compatibility with Holley 4150 and 4160 carburetors makes it a drop-in solution for builders standardizing on these proven carb platforms. Installation requires basic hand tools and careful attention to flare fitting torque specifications to prevent leaks; proper seating of 5/8-18 inverted flare connections ensures long-term reliability and safety during operation.
