Protect your carbureted fuel system with the Earl’s Vapor Guard™ 3/8" Fuel Hose, engineered to withstand today’s harsh fuel blends. Modern fuels with ethanol and additives can quickly deteriorate standard rubber hoses — leading to leaks, fuel loss, and potential injector clogging. Earl’s Vapor Guard hose eliminates these problems with advanced multilayer barrier technology for long-term durability and vapor control.
This innovative hose features a three-layer construction:
A Primary Barrier Layer that resists heat and aggressive fuel additives
A Thermoplastic Vapor Guard™ Barrier that prevents fuel permeation and vapor loss
An Exterior Cover Barrier that protects against ozone and extreme temperatures
Designed for carbureted systems (up to 50 PSI), this hose provides a reliable, economical solution for performance builds, classic restorations, and motorsport applications.
Features:
- 3/8" fuel hose rated for carburetor systems only (not for EFI use)
- Advanced multi-layer design prevents vapor escape and hose degradation
- Compatible with bio-fuel, diesel, race gas, E85, and pump gas
- Durable outer layer resists ozone, heat, and abrasion
- Maximum pressure rating of 50 PSI with a temperature range of -40° to 257°F
