Earl's Performance Ano-Tuff Carburetor Fuel Line Kit

Earl's Performance Ano-Tuff Carburetor Fuel Line Kits bring professional AN plumbing technology to your fuel system in a convenient, pre-assembled format — purpose-built for street performance, racing, and marine applications that demand clean, reliable fuel delivery. Each kit arrives ready to install, eliminating the guesswork of sourcing and assembling individual components for a factory-quality result right out of the box.

At the heart of every Ano-Tuff kit is Earl's proprietary MIL-SPEC Type III hard anodized finish — a military-grade surface treatment that penetrates deep into the aluminum for outstanding wear resistance and long-term corrosion protection. This coating stands up to aggressive fuel additives, alcohol-based fuels, and the harshest racing environments.
