How-To: AN HOSE, RUBBER-CORE FUEL SPRINKLER!
December 20th, 2011
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.
