Single Feed Fuel Line W/ gauge Port 1/8in

The SPECTRE Single Feed Fuel Line with gauge port 1/8in (MPN SPE-29883) is a precision fuel manifold designed for carbureted engine builders and restoration enthusiasts working with Holley single-feed carburetor applications. This component consolidates fuel delivery and monitoring into one compact assembly, eliminating the need for multiple fittings and reducing potential leak points in your fuel system. Whether you're tuning a street-strip cruiser, a vintage hot rod, or maintaining classic automotive machinery, this fuel line simplifies plumbing while providing real-time fuel pressure visibility through its integrated 1/8 inch NPT gauge port.

Built from chrome-plated steel for corrosion resistance and durability, the single feed fuel line features a 3/8 inch NPT female inlet for primary fuel supply connection and dual 5/8-20 inch outlets to feed the carburetor's fuel bowls independently. The 1/8 inch NPT gauge port allows direct mounting of a fuel pressure gauge, enabling you to monitor system pressure and diagnose lean or rich-running conditions without installing external T-fittings. The chrome finish not only enhances underhood aesthetics but provides a protective barrier against fuel system corrosion—critical for vehicles exposed to ethanol-blended fuels or stored seasonally. Steel construction ensures heat stability and longevity compared to plastic alternatives.

This fuel line is specifically engineered for Holley single-feed carburetor platforms and fits seamlessly into systems where centralized fuel distribution is preferred over individual line routing. Installation requires basic fuel-system knowledge and proper NPT thread sealing compound; the compact 6 x 1 x 8 inch footprint fits neatly in tight engine bays typical of classic and modified vehicles. Ideal for builders upgrading carb fuel delivery, transitioning from multi-point systems, or replacing corroded original manifolds, the gauge port integration eliminates guesswork during tuning and provides insurance against fuel starvation issues. This assembly is a must-have for anyone serious about carburetor engine reliability and performance diagnostics.
