Tech 101: Fuel-Line Hose – The Best And Worst Material To Use.

Fuel-Line Hose Features

The fuel-line hose is mainly used for transferring fuel from the storage tank at a fuel pump into vehicles. Reinforced rubber is one of the most common material that is used to make this hose. This kind of rubber helps in preventing spillage and any kind of kink. A few features of fuel-line hose are as follows.

  • It should be flexible
  • The hose should most importantly be resistant to fire, ozone, and permeation by alcohol blended gasoline and diesel fuels.
  • They should be available in a variety of sizes ranging from 1/4 in. to 2-3/8 in.
  • Their other important features include weathering, tearing, impact, abrasion, radiation exposure, oil, grease and fuel resistance.
  • The hose should be lightweight.
  • The hose should have a high-pressure suction and discharge.
  • A required 250 to 3,000 psi working pressure and -40 to 100 degrees C temperature.

Type Of Material We Should Use

Polytetrafluoroethylene (PTFE) most commonly known as Teflon, which is the plastic with the lowest coefficient of friction. Used as a coat in vessels or wires to make them waterproof. It is one of the safest fuel-line to use. PTFE shall prevent the hose from burning. The braided stainless steel lines are an excellent way to replace rubber hoses manufactured in factories like rubber fuel lines, clutch, and brake lines. Comparatively more chemical -resistant and pressure resistant to the other stainless steel lines. They’re a little harder to install.

Rubber tends to bulge or deteriorate with age, but PTFE fuel-line hose does not. The steel outside maintains a uniform inner diameter. This allows for faster fluid transfer. The stainless steel outside makes the lines looking sparkly and shiny, giving it a brand new and very professional look all the time. This shall also prevent inner hose damage.

Type Of Material We Should Not Use

Neoprene rubber fuel line, these were the only fuel lines used earlier when the quality of fuel was still good. Nowadays, with reformulated gasoline distributed across the country, there are dozens of different blends of gasoline. They depend and defer upon geographic locations and smog levels. This has altered the quality of gasoline due to which it has undergone a major change.

Today, all types of gasoline used as a form of fuel in vehicles, are blended with 10 percent of ethanol. Ethanol enhances the octane rating and has gained a lot of attention to be an octane booster that affects older fuel systems. Nevertheless, changes in blending fuel will take a toll on this style and the quality of fuel line used as well. Earlier the rubber fuel line let the fuel vaporize seeping through the hose into the atmosphere which gave a gasoline smell even when it was not in use. Hence, the new fuel-line hose is safer and environment-friendly following safety measures.
