Vapor Guard

Modern fuels are the enemy of traditional rubber hose (including steel-braided hose) causing deterioration. Rubber hose must be inspected and replaced frequently to eliminate the safety hazards associated with fuel vapors and leakage that occurs as the traditional rubber liner deteriorates. Use Earl’s Vapor Guard as your long-lasting hose solution!

STOP FUEL LOSS!

A two foot section of traditional rubber fuel hose loses one gallon of fuel per year through permeation. That’s up to one tank of fuel per year for a vehicle plumbed with 24’ of hose!

Features

  • Multi-layer rubber hose designed to withstand to the corrosive properties of modern fuels
  • Multi-fuel compatible: Approved for use with leaded and unleaded Gasoline, Diesel, Biodiesel, E-85, 100% Methanol, ETHANOL and gasohol fuels
  • A two foot section of Earl’s Vapor Guard saves one gallon of gas each year as compared to traditional rubber hose from permeation alone.
  • Primary Barrier Liner – initial layer offers high resistance to heat and aggressive fuels
  • Vapor Guard Barrier – Thermoplastic layer provides superior fuel isolation significantly reducing vapors from escaping through the hose
  • Reinforcement braid-aramid material – (EFI hose only) is used to provide the higher pressure rating that is required with fuel injection
  • Exterior cover – provides extreme tolerance of heat and ozone
  • Choose from carburetor or higher pressure EFI hose
  • Hose available in 5/16” and 3/8” sizes

WARNING!

Once fuel lines are degraded, hose particles can contaminate and obstruct fuel injectors and carburetor passages. Vapor Guard provides a three way shield against hose deterioration

Modern fuels are at war with your fuel system. Modern fuels (more than 40 EPA-approved fuel blends in the US alone) include additives that break down traditional rubber hose. This breakdown leads to potentially dangerous leaks & weeping as well as vapors that waste fuel and leave unwanted odors in your shop. Once fuel lines are degraded, hose particles can contaminate and obstruct fuel injectors and carburetor passages. Earl’s Vapor Guard hose and hose ends provide a complete, economical solution that virtually eliminates these fuel permeation issues common with most rubber fuel lines.


Vapor Guard’s secret is in its layers. The innermost Primary Barrier Layer offers high resistance to heat and aggressive fuels. The middle Vapor Guard™ Barrier is a Thermoplastic layer that provides superior fuel isolation and virtually eliminates vapors from escaping through the hose. The Exterior Cover Barrier provides extreme tolerance to heat and ozone giving Vapor Guard a three way shield against hose deterioration.


Matching Vapor Guard hose ends feature a special smooth retention bead that retains the hose under pressure while assuring the hose liner is not damaged. They’re black brite-dip anodized for good looks and corrosion protection. Assembly is a snap! Simply cut the hose, push it on and tighten the clamps! Put Earl’s Vapor Guard™ in your arsenal and defend your ride from modern fuels!
