When it comes to plumbing the fuel lines in your vehicle, safety, longevity, and performance
should be at the top of your list.
Modern fuels have additives that harden and deteriorate traditional rubber hose including
stainless steel braided hose.
This leads to potentially dangerous leaks and weeping.
The fuel vapors also deplete fuel and leave unwanted odors in your shop.
once fuel lines are degraded, rubber hose particles can contaminate and obstruct fuel
injectors and carburetor passages, hindering performance and causing multiple problems.
Earl's performance fuel hose addresses these issues with multi-layer technology designed
to withstand the corrosive properties of modern fuel.
With four new hose options available, let's take a closer look at all the features and
benefits of Earl's performance fuel hose.
Earl's Vapor Guard hose provides an economical solution that virtually eliminates fuel permeation
issues common with most rubber fuel lines.
The technology inside Earl's Vapor Guard hose is in its layers.
The multi-layer rubber hose is designed to withstand the corrosive properties of modern
fuels while eliminating vapors and providing extreme tolerance to heat and ozone contamination.
Vapor Guard hose is available for low-pressure carburetor fuel systems or high-pressure EFI
applications.
It's important to note that they are available in 5/16ths or 3/8ths sizes only.
They are not intended in use in applications where the hose is submerged in fuel.
Vapor Guard hose must be used with Vapor Guard hose ends and clamps.
Using other hose barb style fittings or hose ends may damage the inner liner on the hose.
Vapor Guard fuel hose ends feature a smooth retention bead that retains the hose under
pressure, making them easy to install and use, simply cut out the hose, push it on and
tighten the clamps.
For most economical builds, Vapor Guard is the way to go.
Next in our line is our Speed-Flex fuel hose.
Just like Vapor Guard, Speed-Flex hose is designed to withstand the corrosive properties
of modern fuels.
The carbon infused PTFE inner liner withstands methanol and alcohol much better than Vapor
Guard.
The tough outer stainless braid protects your Speed-Flex hose and provides additional strength
and integrity.
Speed-Flex is carbon lined for safety to eliminate static electricity build up.
With its robust inner liner and stainless steel braid, it is not as flexible as Ultrapro
or Ultra-Flex fuel hose.
Speed-Flex without the PVC coating can be used in applications where the hose is immersed
in fuel.
Speed-Flex hose is intended for use with Speed-Seal hose ends only.
Speed-Flex is a little more difficult to cut and assemble than Vapor Guard.
When you need performance, Earl's Ultrapro fuel hose gets the nod.
The Ultrapro series was engineered to exceed the rigorous demands of racing.
Designed to withstand today's modern fuels, it thrives in harsh environments that include
vibration.
The PTFE double helix inner hose liner offers extreme flexibility, making tough plumbing
jobs a snap.
The liner is carbon infused for static dissipation and has an ultra-low coefficient of friction
for maximum flow.
The outer liner is also reinforced with a glass fiber wrap for additional strength and
integrity.
Nothing has been left to chance with Ultrapro hose.
Ultrapro is also available in a black polyester braid and stainless steel braid.
The polyester braid and stainless steel braid are significantly lighter than traditional
stainless steel protected rubber hose.
Ultrapro polyester braided hose is not recommended for applications where the hose is submerged
in fuel or subject to road debris.
Ultrapro fuel hose must be used with Ultrapro hose ends.
Save weight and get the flexibility of Ultrapro fuel hose for your racecar.
Twist on hose ends can be easily assembled at home with common tools.
Ultrapro is easier to cut and assemble than Speed-Flex, but not quite as easy as Vapor
Guard.
Earl's Ultra-Flex is the finest and lightest fuel hose available in either a woven kevlar
braid or a high tensal grade 304 stainless steel braid.
For increased flow, the PTFE tubing has a smooth internal bore.
The convoluted exterior makes for incredible flexibility for making those tight radius
turns.
The inner PTFE tubing is suitable for use with any fuel and resits temperatures up to
500 degrees Fahrenheit.
Ultra-Flex kevlar braided hose is not recommended for applications where the hose is submerged
in fuel or subject to road debris.
Our kevlar braid hose is 60% lighter and our stainless braid hose is 40% lighter.
When it comes to maximum performance, no other fuel hose comes close to Ultra-Flex.
As with other Earl's fuel hose, it only accepts Ultra-Flex crimp style hose ends.
Ultra-Flex assembly is more difficult and requires a specialized crimping machine.
For maximum weight savings and flexibility, use Ultra-Flex fuel hose.
When plumbing your vehicle, always keep fuel hose away from heat sources, sharp edges,
and moving components.
Always allow enough slack for powertrain movement.
For fuel hose that is subjected to road debris and high temperatures, use stainless steel
braided fuel hose or a hard line.
Make sure to use the clamps to hold the hose in place and prevent abrasion.
Clamps also help in dampening vibration to other components, use proper bulkhead fittings
or grommets when the plumbing goes through a panel.
Save time and money by choosing the right fuel hose for your vehicle and have that piece
of mind knowing it was done right.
