If the clamp band is loose, apply oil to the screw

has been used much or not. Replace the rubber
fuel lines and clamp bands every two years.
If the fuel lines and clamp bands are found worn
or damaged before two years' time, replace or
repair them at once. Bleed the fuel system after
replacement of any of the fuel lines, see TO

or paper to prevent dirt from entering the lines.
Dirt in the lines can cause fuel injection pump
