When I replaced the lines in my 84 with it's Golf motor, the protective
sleeves over my fuel lines were missing altogether in some places.  I used
some drip irrigation water line to prevent chafing of the actual line.  Home
Depot or True Value or your local irrigation store has it.  Probably not the
best stuff in the world for the task, but easy to use and inexpensive.
You should use stainless steel hose clamps on the fuel lines.  I get mine
from West Marine, but they probably aren't the most economical supplier.
When messing with fuel lines, a golf tee or two can be used to stop the flow
of gas.  I put  some in my tool box always, and I don't even do golf.
