Safety precautions


WARNING!

When removing and installing fuel pump or
fuel gauge sensor from a partially filled fuel
tank:

BEFORE beginning work, place exhaust
extraction system suction pipe near fuel tank
opening so escaping fuel vapors can be
immediately sucked off.
If no exhaust extraction system is available,
use a radial fan (with motor located outside
airflow) with volume of at least 9 cfm.
Wear fuel-resistant gloves whenever working
with open parts of the fuel system.

Be sure the ignition is switched off when:
Disconnecting fuel injection system wiring.
Connecting or disconnecting test equipment
leads.
