Video: Eliminate Fuel Odor and Leaks With Earl’s Vapor Guard Hose


We learned the hard way. At one point we had stainless braided fuel line on Project Orange Crush. It was fuel line we picked up used, but was in like new condition. We spent a few hours routing the line, making fittings and mounting the line. We also had sore finger tips from the stainless poking us. When we were all done it looked beautiful but was a major fail.

After a few days of the new stainless braided fuel line on Orange Crush, we noticed our garage smelled like fuel. We spent another couple hours trying to find a fuel leak, which was non-existent. It was not until a friend stopped by and told us that it was probably gas permeating through the fuel line. 

We were sicken to think of all the time and money we spent installing the new line just to make things worse for Orange Crush. Come to find out, a 2ft piece of rubber hose can lose a gallon of fuel over the course of a year due to permeation. At the rate we could smell gas, we were probably leaking a gallon a week. 

We know that we are not the only ones in this situation. Todays pump gas can contain up to 10% of ethanol. Ethanol is not a good additive for our classic Mopars. Ethanol gradually dries out your fuel lines as fuel vapor seeps through them. This leads them to harden and crack, increasing the chance of a dangerous fuel leak. 

Earls Vapor Guard hose cures all of these problems. Earls Vapor Guard hose and fittings have been designed for todays fuels and at an affordable price. Earls Vapor Guard hose is made up of four distinct layers, solving the problem of permeating fuel. 

The innermost layer or Primary Barrier Liner, offers high resistance against aggressive fuels and heat. The second layer is the thermoplastic Vapor Guard Barrier, isolates the fuel in the hose and stops almost all vapors from escaping to the outside.

Surrounding that barrier is the Reinforcement Braid, which is available in two different versions. One version is designed for use on carburetor fuel systems and can withstand up to 50psi. The second version features woven Aramid fiber and can withstand up to 225psi for fuel injection systems.  

The last layer or Exterior Cover is designed for extreme tolerance of heat and ozone. This layer keeps the Vapor Guard hose from breaking down on the out side from heat and the atmosphere. 

Earl’s Vapor Guard hose achieves all of this with basic installation. The hose can be cut with a basic hose cutter and fittings slide right on. No special tools needed. The special Vapor Guard fittings feature a Vapor Guard Retention Bead to insure the hose stays in place under pressure without damaging the inner liners like a barb fitting. 

Depending on your specific needs, Earl’s Vapor Guard clamps are offered in three different styles. You can get the clamps in either a screw-on style, single crimp or dual crimp. The crimp style clamps will need a hose clamp plier tool, which Earl’s also offers here. 

The best part is Earl’s Vapor Guard hose, clamps and fittings will not break the bank. A kit containing 20ft of EFI-grade hose, four fittings, clamps and an inline fuel filter, enough to plumb a car and a returnless Sniper EFI system, costs less than $170, compared with more than double that figure for a premium, stainless-steel-braided alternative.
