Earl's Performance Vapor Guard EFI Fuel System Plumbing Kits

Earl's Performance Vapor Guard™ EFI Fuel System Plumbing Kits deliver a complete, ready-to-install solution for builders converting from a carburetor to Electronic Fuel Injection (EFI). Built around Earl's proprietary multi-layer Vapor Guard hose technology, these kits are engineered to withstand the demands of modern fuel formulations — virtually eliminating the fuel vapor permeation and liner degradation that plague conventional rubber fuel lines.

Why Vapor Guard Technology?

With over 40 EPA-approved fuel blends in use across the United States, today's fuels can aggressively attack and break down traditional rubber hose from the inside out. Liner deterioration leads to dangerous fuel weeping, unwanted odors, and contamination of precision fuel injector components. Earl's Vapor Guard hose is engineered specifically to combat these issues through a proven multi-layer construction that delivers long-term reliability in high-performance applications.

Vapor Guard Hose Construction:

• Primary Barrier Liner — The innermost layer provides high resistance to heat and aggressive modern fuel formulations
• Thermoplastic Vapor Guard Barrier — A mid-layer thermoplastic barrier that virtually eliminates fuel vapor permeation through the hose wall
• Aramid Reinforcement Braid — Delivers the high-pressure rating required for fuel injection systems
• Exterior Cover — Engineered for extreme tolerance to heat and ozone for lasting durability
• Vapor Guard Retention Bead — Retains the hose under pressure while protecting the inner liner during assembly

What's Included (Varies by Kit Configuration):

• Vapor Guard EFI fuel hose compatible with modern fuel types (compatibility varies by kit — verify individual listing for E85 suitability)
• Electric inline fuel pump designed for frame rail installation
• Billet aluminum pre- and post-fuel filters with washable and replaceable bronze filter elements
