Earl's Performance Vapor Guard Carburetor Fuel Hose

Earl's Performance Vapor Guard Carburetor Fuel Hose is a purpose-engineered fuel line solution designed for carbureted fuel systems in automotive, racing, and high-performance street applications. With over 40 EPA-approved fuel formulations in circulation across the U.S., conventional rubber hose is no match for today's aggressive fuel chemistry — leading to liner deterioration, dangerous leaks, and fuel vapor permeation. The Vapor Guard line is built to stand up to all of it, delivering a long-lasting, leak-resistant fuel line for the demands of modern pump fuels and performance builds.

Three-Layer Barrier Construction:

• Primary Barrier Liner — The innermost layer provides high resistance to heat and aggressive modern fuel blends, protecting hose integrity from the inside out
• Vapor Guard Thermoplastic Barrier — A middle thermoplastic layer delivers superior fuel isolation, virtually eliminating fuel vapor permeation through the hose walls and reducing unwanted fuel odors and waste
• Exterior Cover Barrier — The outermost layer offers extreme tolerance to heat and ozone for lasting durability in demanding under-hood environments

Key Features:

• Multi-layer rubber construction specifically engineered to resist the corrosive properties of today's fuel blends
• Broad fuel compatibility — approved for use with leaded and unleaded gasoline, diesel, biodiesel, E-85, 100% methanol, ethanol, and gasohol blends
• Dramatically reduces fuel vapor permeation compared to traditional rubber hose, improving efficiency and reducing fuel odors
• Helps prevent liner degradation that can shed particles into carburetor passages and obstruct fuel flow
• Maintains flexibility for straightforward routing in tight engine bays
• Must be used with Earl's Vapor Guard hose ends and clamps — other barb-style fittings or hose ends may damage the inner liner

Earl's Performance, a cornerstone brand within the Holley family of performance brands, has been trusted by builders and racers for decades. The Vapor Guard Carburetor Fuel Hose line is available in multiple configurations to suit a wide range of carbureted builds — providing a complete, modern fuel line solution that stands up to today's pump fuels and high-performance demands.
