[alfa] 164 fuel line hasn't leaked yet

["Daegrigg (Don)" <daegrigg@xxxxxxxxxxx>]

Never had a fuel leak with any of three 164s.  I use standard clamps and
5/16  FI hose.  I wonder if some leaks are due to excess engine movement
(bad motor mount or t-bone) and/or the fuel rail supply hose anchored too
tightly to the engine bay.
