WARNING
EWA13850
Gasoline is extremely flammable and under
certain circumstances there can be a danger
of an explosion or fire. Be extremely careful
and note the following points:
• Stop the engine before refueling.
• Do not smoke, and keep away from open
flames, sparks, or any other source of fire.
• If you do accidentally spill gasoline, wipe it
up immediately with dry rags.
• If gasoline touches the engine when it is
hot, a fire may occur. Therefore, make sure
the engine is completely cool before per-
forming the following test.
1. Disconnect:
• Fuel pump coupler
• Fuel sender coupler
(from the wire harness)
2. Remove:
• Fuel tank
3. Check:
