Hi guys,

What is the best practice in relation to keeping or disposing of the fuel
line sheathing which presumably protects the fuel line as it travels to the
fuel injectors across and around the air distribution system in the engine
compartment?  I remember reading past posts about a weird interaction
between some nylon fuel hoses and the sheathing which produces a brownish
residual almost like the hose is melting or slowly disintegrating.

I replaced my fuel lines about four years ago with a good product for fuel
injection but I'm looking to replace sections of hose again because I am
noticing areas of this gummy phenomena. I am leaning toward replacing my
hoses with the knitted / braided cloth FI hose instead of the more
expensive nylon fuel injection hose and I'm thinking of completely doing
away with the sheathing.

What sayeth the list?

Thanks,

BT
