Preparatory Steps
WARNING
Fuel is flammable. Keep all cigarettes, flames, pilot
lights, arcing equipment, and switches out of the
work area and areas sharing ventilation to reduce the
possibility of severe personal injury or death when
working on the fuel system.
CAUTION

lines, replacing filters and priming the fuel system
that fuel is not spilled or drained into the bilge area.
Do not drop or throw filter elements into the bilge
area. The fuel and fuel filters must be discarded in
accordance with local environmental regulations.
