When I did the fuel hoses on my 2.1, since I rerouted the hoses
somewhat, and after much internal debate, I chose not to reuse the
existing (and in poor condition) OEM sleeves. Instead I cut off good
sections of the OEM sleeves using them to protect the hoses at certain
spots.
I cable strapped the hoses to the intake runners (a la the tencentlife
rebuild) but put split sections of left over hose between the cable
strap and hose. Likely overkill, but to my mind, this spreads out the
pressure of the cable strap *a little* and provides a smoother point
of contact. I'm NOT saying that using cable straps alone is bad! This
was just a preference of mine.
I mention all this as I've seen discussion on whether or not one
should reuse the sleeves. Some have experienced oozing issues possibly
due to the newer type gas fuel blends used and/or poor quality new
hose. In my case, the sleeves were pretty badly heat damaged and in
certain spots, wouldn't even fit over the new hose! My take on why VW
sleeved the hoses was to protect them from chafing and possibly from
"contact" heat from the engine block. The latter being one reason I
rerouted the hoses (keep them above and away from the engine block)
Please bear in mind that I'm a "shade tree" type at best and not an
expert. YMMV. :^)
I used 5/16" Gates Ethanol blend rated hose and proper fuel injection
type clamps. This hose "meets SAE 30R9 requirements & CARB CU-06-002
for low permeation."
