Fuel Lines

Welcome to our Harley Fuel Lines collection — your go-to source for high-quality fuel hoses, lines, and components designed for Harley-Davidson motorcycles. Whether you ride a classic Sportster, a touring bike, or a custom build, having the right fuel line ensures consistent fuel delivery, reduces leak risks and supports safe, reliable engine performance.

Why Fuel Lines Matter on a Harley

• Safe & Consistent Fuel Delivery. The fuel line (or “fuel hose/pipe”) transfers gasoline from the tank to the carburetor or fuel-injection system. A proper fuel line maintains consistent flow without leaks, kinks, or degradation — critical for smooth running and preventing fuel starvation. 

• Protects Against Wear, Fuel Degradation & Ethanol Issues. With modern fuels (often containing ethanol and additives), standard low-quality hoses tend to deteriorate, crack, or swell — risking leaks or vapor permeation. High-quality, fuel-rated lines keep fuel contained, resist chemical damage, and handle the pressures and heat of a motorcycle fuel system.

• Improved Durability & Safety. Compared to old or degraded rubber hoses, high-grade fuel lines — braided, PTFE-lined, or otherwise reinforced — offer better resistance to abrasion, heat, pressure, and long-term wear. That means less maintenance, fewer failures, and safer rides.

• Better Fit for Custom Builds & High-Performance Rides. If you’re modifying your intake, carburetor, or using high-octane fuels, a properly rated and sized fuel line ensures stable fuel flow even under increased demand or pressure — helping avoid performance issues or engine strain.

Whether you’re doing maintenance, upgrading a custom chopper, or restoring a classic, the right fuel line makes a big difference in reliability and safety.
