This video shows what happens to rubber-core, braided steel hose after exposure to today's street gas.
This car was completely rebuilt 6 months ago with a new LS V8 powertrain and all new rubber-core, braided steel AN fuel hose. The vehicle had been sitting for a few months when the owner went to pull it out of the shop--with a big surprise!
Needless to say, he is VERY lucky to have quickly realized he had a 'fuel sprinkler' system under his hood! This is how rubber-core AN hose fails with today's fuels--it starts to weep fuel in the beginning, then quickly turns into a complete 'leaker' hose.
This is why you run conductive-core, PTFE fuel hose--it is built to handle today's fuel.

You can check out www.techafx.com for good looking, easy to install BlackWrap or Braided Stainless Steel PTFE AN Hose and their all-black TechAFX aluminum AN fittings--all TechAFX products are Made in the U.S.A.

  • Ethanol is one of the reasons, but there are other chemicals that are added to street fuel (to promote complete combustion) that destroy rubber hose--that's why all new cars (both gasoline and diesel) come with conductive-core, PTFE hose: it is the only hose that will last with these additives.

    This is an issue that is more common than most people know--it just hasn't gotten a lot of exposure.
